Headlights on C5 Vette

Robert Thomas

The lights initially sent me did not work.. Anthony sent me pigtails which made the system work. The low beams illuminate the road so much better without blinding oncoming traffic.

Did not for for a 1991 Toyota MR2 T

Alexander Mastalarz

I bought this item to fix a high beam indicator dashboard light glitch due to having LED headlights. It did not work. It actually made the headlight it was plugged into not work at all.

Not sure about this

Ron Fox

I installed these to get rid of a flickering problem that started about 2-3 months after bulb install. Altho the flickering seems to have gone away, i also did not have hi-beam function afterwards. This was all on a 2003 montana with no canbus system. But i was told the resistors would help even out the voltage input, if nothing else. Currently waiting on new bulbs to try out since losing hi beam function

50 watt resistor T-harness--

Stephen Miller

The install took a little more work & time than I expected. The T-harness snapped in place easily enough, but finding a place to zip tie the two resistors was another problem. They got very hot, so I separated them a little to allow air flow around each and zip tied them in place. The fog light now work but, I am concerned about the heat generated during the summer. I hope they hold up to the head under the hood.
