The anti flicker was wired wrong The anti flicker was wired wrong. I had to switch the pins so positive and negative plugged in correct. When installing it didn't work and took me a bit to figure it out. Once corrected lights work fine. So that tells me it wasn't tested before sent out from manufacturer.

My fault, made right! I placed an order for my daughter's car. Got the bulbs delivered very quickly. Simple install. Went well but the output was far from what we were anticipating. I went back on their website and contacted their customer service. VERY quick response! Come to find out, I ordered the wrong type of bulbs for the type of headlight assembly that we have (Projector vs Reflector). Kevin made everything right for me by suggesting the type of bulb (HID) we should use and also by taking my return back because of my mistake. Thank you Kevin and thank you XenonPro. We will be doing more business down the road for sure!

Great product & service I had a very bad experience at the beginning as it’s very annoying to get tech support through chat only, as one of my lights where not working. As long as you give yourself lots of time, they will go step by step to find the exact issue. Unfortunately in my case it was not an installation issue, it was a defaulty ballast. But once they found the issue, they kindly sent out a replacement part right away. I really appreciate having good service and good quality products. Their products are definitely worth the price. And having peace of mind, knowing that they will replace any defective part with out hesitation as long as you take time and go through their tech.

Issues on 4300K HID We have been using Xenon Pro HID's for almost a year now. The first set worked well so we ordered more sets for the rest of our trucks but the lasts sets have brought us a lot of trouble. The bulbs didn't always light up on some of the sets and another issue is that the lifespan of these bulb is only around 100 to 200 hours which I hope they will improve.

We also installed the Anti-Flicker harnesses but that created a 2 second delay when lights were going from Hi-beam to Lo-beam. Per Chat room recommendation, removed the Anti-Flicker device and lighting delay is now resolved. Note: Don't forget to remove the glass shipping lens at installation.
