A little too well. - So far, these have been mighty fine bulbs on my '13 JKU Rubi although I would not use them with the stock 16ga wiring. With the PWM, your not getting even close to their full potential since voltage and current is limited. I upgraded to the Hella Vision plus housings, which made quite the difference themselves, using the included H4 bulb and stock wiring. You will need to get an H13 to H4 pigtail for this to work. Then I installed an upgraded wiring harness and installed the 100/80's in the Hella housings. On low, these things are now cutting through the dark like sunrise and with the Hella housings, the light is focused with a nice cut-off so I'm not blinding traffic. On high beam, they throw farther than I can see. Even with the light flickering problem from the PWM since I don't have a capacitor installed yet, the difference is dramatic. Yes, you will need an anti-flicker on the harness upgrade since the PWM really messes with the load relays needed to run full current to the higher output bulbs. They flicker just like LED's since the relay's are turning on and off so fast it sounds like a bee buzzing. Hopefully my 2nd order for the anti-flicker device will be here tomorrow since my first order was through an 'overseas' supplier and is still over a month out. The one major problem I'm having is that when driving the back-roads, bugs come from miles and it sounds like I'm going through a rain storm. I've had to start carrying around a gallon of washer fluid as I go through so much now. Edit 1.0 - I received the Rigid anti-flicker device and I guess the more stable current really brought these 100/80's to life. The relay buzzing was cured instantly. I pulled them and reinstalled the factory wattage Hella bulbs. With the updated harness and the Rigid anti-flicker installed these were just too bright to run on the highway. My goodness they got hot! To the point even with the upgraded wiring I was concerned of melting something. I could not touch the Hella glass reflectors without causing pain. It's fortunate I did swap back because these bulbs running 'wide open' charred the ground plug slot on my ceramic H4 connector after a 30 minute road test. The stock bulbs with the upgrades are giving me more than enough light to see by and although under the right connection conditions these 100/80 will throw incredible light, they had to go. Also, now I don't have to worry so much about Mr. D.O.T. officer saying hello to me. If I ever run the Baha in my Jeep, I will put them back in with even heavier upgraded wiring but for now they will just collect dust on the shelf. Review: H4 100/80W, low beam comparable to LED brightness - H4 100/80W This bulb would be a god sent for motorcycles, only if it came in the fog/french yellow too... The low beam is properly positioned, quite bright and whiter than I expected from an incandescent. The high beam is also properly positioned, the mirror seems to focus it just like a DOT 60/55W bulb, no funky blinding patterns or wide spread beam as experienced with some LEDs. My intent was a brighter low beam and I am satisfied... I have tried a number of LEDs and it is comparable in luminosity/visibility. With LEDs I was not satisfied with the high beam as my mirror would not properly focus the beam, so I kept using 60/55W after testing 3-4 brands, the high end models. This 100/80W does not suffer from that. It is considerably brighter than a regular 60/55W, in fact some white road signs seem to reflect back almost too much light... It may be distracting at first.. It does not seem to heat up in a ridiculous manner. In theory it should put out ~60% more heat and light than the typical H4 so check your equipment after a few uses if it has completely enclosed headlights... For setups that keep both low and high beams ON, double check the values of the fuses as it may blow the typical 10Amps... Divide wattage consumed by the volts supplied to find the amps required for the fuse. 100W/12V=8Amps, 80W=7Amps, both ON = 15 (in reality the voltage is between 13.4-14V for a running motor, I don't know at what voltage the fuses are measured) Also, if possible degrease the bulb before installation w/ acetone, isopropyl alcohol, contact cleaner, etc, as oily spots on glass create hot spots. Be safe, have fun. ## Features - HIGH WATTAGE OUTPUT: Delivers increased brightness compared to standard halogen bulbs for maximum visibility - BUILT FOR DEMANDING USE: Ideal for off-road, industrial, and specialty lighting applications - ENHANCED VISIBILITY: Provides stronger illumination in low-light and extreme conditions - DURABLE PERFORMANCE: Designed for reliable operation in rugged environments - CHECK COMPATIBILITY: Higher power draw may require proper fitment verification before installation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000COBLKW | | Auto Part Position | Rear | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #85,069 in Automotive ( See Top 100 in Automotive ) #468 in Automotive Headlight Bulbs #641 in Automotive Headlight Assemblies | | Brand | Hella | | Brand Name | Hella | | Brightness | 100 lumen | | Color | Multi | | Customer Reviews | 4.4 out of 5 stars 670 Reviews | | Fit Type | Vehicle Specific Fit | | Global Trade Identification Number | 00760687143574, 00760687781592 | | Included Components | 2 Bulbs | | Item Package Quantity | 1 | | Item Type Name | Headlight Bulb | | Item Weight | 9 g | | Light Output Maximum | 100 lumens | | Light Source Type | Halogen | | Manufacturer | Hella | | Manufacturer Contact Information | PEACHTREE CITY, GA, 30269 US | | Manufacturer Part Number | HELAH3130WTB | | Model Number | H4 100/80W | | Number of Items | 2 | | Number of Packs | 1 | | OEM Equivalent Part Number | H4 100/80W | | Operating Life | 50000 hours | | Package Quantity | 1 | | Specific Uses For Product | Fleet and plant maintenance. | | UPC | 760687781592 760687143574 | | Unit Count | 2 Count | | Voltage | 12 volts | | Wattage | 80 | ## Product Details - **Brand:** Hella - **Brightness:** 100 lumen - **Light Source Type:** Halogen - **Specific Uses For Product:** Fleet and plant maintenance. - **Wattage:** 80 ## Images ![H4 100/80W High Wattage Bulb, 12V - Image 1](https://m.media-amazon.com/images/I/81xrr6NwdaL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Has anyone tried this bulb on an BMW G650GS? I am a bit concerned it might fry the wires, reflector or lens.** A: You MUST use 12g stranded wire with quality insulation to each h4 socket terminal. You MUST use Ceramic High Heat HD socket. You Must usea relay that is 20% Higher rated than the max amp draw. Your altenator or generator must have the added capacity so to cover the increased draw@ idle of these lamps or they will draw down the battery. If smaller wire or alt capacity there will be voltage drop which increases amp and thus heat. For 1 light on a bike figure for 13.5v to be safe which adds to 9.6 amps. Use a 15 amp relay. For high low you need 2 relays use two 15a or 1 15a hi and 1 10a lo. If its 2 for a dual lamp or 4wheel vehicle double Watt so 260w÷13.5=17a. Best use 25 or 30a relay for high and low. Ideally use a dual output relay so 1 12g lead to each bulb from relay term not daisy chained. Ideally run 10g from battery or alt post to relay input. Built like this you will never have a capacity or heat issue when in good condition. YOU CAN NOT USE ANY STOCK WIRING HARNESS!! NOT EVEN MOST PREBUILT HD WIRING HARNESS. If you follow the above general guide with properly crimped connectors it will not only not burn up but 2 Will have much higher light output. Remember a 5% drop in voltage = a 15% drop in light output 1:3 ratio. Ideal voltage is 14.5V on 12v systems. **Q: I have an original stock headlight. Anything special i need to do to use this bulb?** A: The current draw with this bulb is more than stock so after having the lights on for say a 30 minute drive in warm weather see if the connector at the bulb is hot as well as the wires going to it with the lights still on if so you should install a hevi-duty connector and wire kit. My jeep 2005 wrangler handled these bulbs just fine and I think most vehicles will need nothing.....DBW **Q: I have a 1998 Kawasaki Vulcan 800 Classic. Any need to upgrade anything electrical or does this simply replace the stock bulb? Thanks** A: Oh yeah. You should not just plug this in and go. These bulbs make a ton more heat than a stock 55/60 bulb. Buy a ceramic plug as well, otherwise the stock pug will just melt over time. I think I paid maybe 12 bucks for 2 ceramic H4 plugs on Amazon. **Q: Will these work on my motorcycle? it's a 2004 bmw r1150r, and h4 is stamped on the glass plate of the light housing** A: The h4 bulb will fit, May want to check the wattage they get kind of hot. There is a lower watt bulb too I believe. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I can see!

You almost can't over-drive it on high-beam, certainly not at the speed limit. On low beam at less than highway speeds, it lights up a lot of the area in front and to the side, and is more than adequate, REALLY out performing the stock lamp. No one has flashed their high beams at me, indicating this lamp is too bright in their eyes, which I was originally concerned about. It uses a lot more wattage, but it's within the capacity of the electrical system, and has caused no problems. I've used it many months now, and it still works (on all of the time). I'll never ride without this lamp. If it goes out, I'll get another. It's fantastic. It's a lot cheaper way to go than LED's, and likely provides a better light. ## Frequently Bought Together - Hella H4 100/80W High Wattage Bulb, 12V - True Mods H6054 H4 LED Headlight Wiring Harness [Negative Switched Conversion] [Fused] Universal H4 Head Light Relay Harness Kit for 9003 H5054 H6054LL 6014 H6024 6052 6053 Subaru Toyota Jeep Headlamp - HELLA 003427811 Hlmp Kit 190X132Mm H4 12V Ece, Multi --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1185379-h4-100-80w-high-wattage-bulb-12v](https://www.desertcart.co.uk/products/1185379-h4-100-80w-high-wattage-bulb-12v) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-10-29*
