The brightness is equal, and I replaced the bulbs in my overhead cabin map/courtesy light fixture. I had to crimp the socket blades a bit to get a good grip on these lights, but they work well. Very pleased. Just aim them where you want the light to go in your fixture as these are not cob led lights. There is no flickering, the color is a bright white, and they are compatible to my gixtures. ## Features - ✔【High Quality & Low Power】Pack of 4pcs 578 led Festoon bulbs, 6000K White, 400 Lumen, 1.5W/Bulb, Bulb size: 1.65" x 0.33",Working voltage:Dc 12v.

These are so bright, it feels like daylight in there. A couple of very cool things about this bulb are 1) you can spin the bulb in the clip/outlet to adjust the amount of light you get - in case it's too bright (seriously), and 2) these run very cool and draw almost no power so they won't eventually cook your plastic light cover, and you can leave your dome light on for days or maybe weeks without it drawing down your battery. ## Frequently Bought Together - Serundo Auto 578 Led Bulb 211-2 41mm 42mm 1.65in for Car Map Light Dome Light, 6000k White Super Bright Interior Led Festoon Bulb,Pack of 4pcs - Marsauto 194 LED Bulb 6000K White 168 T10 2825 W5W 5SMD Replacement Bulbs for Car Dome Map Door Courtesy Side Marker Reading Glove Box License Plate Lights (Pack of 10) - iBrightstar 9-30V Super Bright Low Power 3157 4157 3057 3156 LED Bulbs with Projector Replacement for Back Up Reverse Lights and Tail Brake Parking Lights, Xenon White --- ## 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/159340866-42mm-578-led-bulb](https://www.desertcart.co.uk/products/159340866-42mm-578-led-bulb) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-28*
