### ⭐⭐⭐⭐ 







  
  
    Simple but good!
  

*by A***S on September 14, 2014*









  
  
    Single beam harness is for TWO headlights . I ordered two of them as I am one whom has an issue with one light going out. cheap Chinese stuff or quality German Philips set up (which I like better btw, 35w over the overdriven 55w systems) one light wouldn't get the current after that initial "pop" on... so I wrapped the "other side from the battery" (long cord) up on each, wired em up directly from each headlight control/supply line and ran/extended the power line from the non battery side, and were good to go so far!!cables themselves are simple enough (as compared to the Morimoto Harness which has a double rely system, I took out) the connections into the "relay block" aren't very secure but once they are connected work like a charm!

    Cheaper isn't always better..
  

*by B***K on September 30, 2017*









  
  
    Super cheap! ..but you really get what you pay for with this purchase. I've had to replace or repair every single connector including the relay. They are all super cheaply made and the pins loosen up over time in the plugs. It's perfect length and fits a full size truck really well, but beware it won't last forever and once you start  reading repairs the price no longer seems worth it.
  


### ⭐⭐⭐ 







  
  
    not the neatest looking loom, needs more length and has one input
  

*by E***N on February 4, 2015*









  
  
    Works fine but really not the cleanest looking loom out there. I bought it to wire hid fogs to a dodge ram. The loom was only just long enough running the most direct way, not the neatest. Relay was cheap junk, replace when you install or expect a failure at some point.Only has one input plug from the power side of the light so if you have error lights, there probably going to show up.Plugs were all a good fit and quality.Power and neg wires from relay really quite short also.Overall it did the job but was a pain as there wasn't spare length to make the install as neat as the factory wiring like the ddm harnesses I used for my low and high beams.
