Rusted and sparks
Parts of relays have started to rust after 2 months.One of the relays came faulty and sparks. This could cause a serious issue.

Regarding Installing on a Jeep Wrangler YJ
1.) You will need to extend the wire that goes to the Positive Terminal of the Battery (Amazon clearly pointed out that this item would not fit a Wrangler YJ.)2.) When you do this, you will discover that there is a very large amount of insulation on the Red wire that goes to the Positive Terminal on the Battery and a very small amount of copper inside the Red wire to carry current. This is the reason for the loss of a star.All that being said, the harness works well and stopped the issue with the bright lights cutting out after being on for 10 minutes.

Harness wired wrong at relay - updated
Same issue as one other reviewer; the relays will stick when I turned my highbeams on and I have to completely turn off my headlamps to get the relays to recover and for the highbeams to turn off. This is one of the more expensive relay/harness kits out there and clearly cut corners on the relay quality.UPDATE: dug into this a bit deeper and the relay harness was wired wrong for my 97 Jeep XJ. Low beam ground was in the wrong location. Once I moved the ground all worked well. Product listing says this is compatible with Jeep XJ. Still worth one star.
