    Great product
  

*by J***2 on Reviewed in the United States on December 11, 2019*

When I looked to upgrade my 2001 Silverado 2500hd I first tried HID bulbs & because of the delay in warming I realized only 2 lights worked on hi beam, I just never realized it.  First I changed to LED which were clearer light but was disappointed with hi-beam then I found this kit.Simple installation,  color code didn't quite match instructions but an ohmmeter solved that issue.  And I used heat shrink for weatherproofing.  Once on, I'm really pleased with the results.  They've been on for a year and absolutely no problems.

    1999 Suburban lighting it up
  

*by S***A on Reviewed in the United States on August 2, 2019*

Given I have an older vehicle,1999 Suburban, I am more than happy with the product simply being available.  Both quality and performance are very good, Painless wiring products are excellent.  The instructions did not match up at all with my wiring color but another user had the correct wiring which made the job easy.  The only issue I had was the tap connectors were malformed but I worked through it, my package was an Amazon fulfillment so expect I got a customer return that didn’t make back to Painless.  Seems to happen more often.

    Brings up both high and low beams in the HI setting.
  

*by P***Y on Reviewed in the United States on March 9, 2019*

With the help of readers who answered my question last week, I was able to complete this installation in less than an hour.  I encountered some discrepancies between my vehicle and the instructions.  The yellow power lead from the relay to the low beam lamp I attached to my brown lead (see photo).The high beam wires connected black to the yellow relay wire, and my green wire to the purple relay wire.I'm very satisfied with the results and would highly recommend this kit.TRUCK:1999 K1500 Suburban
