2007 Yukon Denali HIDs Installed, Light Flickering Problem

[Rayaz_XL]

I have a 2007 Yukon Denali, I recently installed a bi-xenon HID kit complete with HID Relay Harness. I though getting a HID kit complete with the relay harness will solve any light flickering problems since it will get it's power source directly from the battery instead of the headlight harness. Wrong.

When I unlock my doors and the courtesy lights come on, the right side HID bulb flickers and goes out. I have to turn the headlights off and on about 5 times, or wait 5 minutes while the engine is running to finally get both lights working. This is not a DRL problem, however I am thinking of removing the DRL Fuses to see what happens. I find this problem embarrasing in such a luxurious vehicle.

After some extensive internet research I found that sometimes, a HID relay doesn't solve all your light flickering problems. What is needed is a special capacitor that stores a power reserve so when you unlock your doors and courtesy lights come on thee is no fight for voltage. Anybody else with similar vehicles have this same problem, and any other fixes? Thank you

whos HID kit did you buy?? and also, im assuming, but verify that you did connect directly to the battery for power, and not from another fused source?

I bought my kit from Mototek Ultra-vision HIDs, excellent quality lights, they just don't work well on my vehicle.

It is recommended to turn-off the approach light feature for the lock/unlock function.

I already did that, didn't want to lose that fancy option. I have to get these lights fixed.

Where are you connecting your ground? I had a similar problem when I first installed my kit. I connected my ground to the chassis of the car where there are paint so I had to sand down the paint to have full metal to metal and no more flickering.

Hey how are you thanks so much for the reply. I grounded my system on a
10mm header panel bolt. I think it is beside the 2 top headlight bolts, it is a spare bolt, not the headlight bolt. What vehicle do you have, and where did you ground your system? Thanks.

The kit I bought off ebay for my Yukon only hooks into the little boxes that come with the kit and then into the factory harness with no ground. I dont know jack about that kind of stuff but they have worked for almost two years now with no problems. I bought a kit for the Avalanche and it requires a ground wire soooooooooo do you really need a ground? Hope you get it fixed that would drive me nuts too.

Alright I checked the ground, upgarded a much thicker ground wire, grounded to solid bare metal, did not help. Went out and bought a 4700uf 35V Capacitor. Still same problem, the right side is flickering and having a hard time starting up especially on cold mornings or nights. Once in a while, the left side will not turn on only the right side.

Next step? I am ordering a HID Anti-Flicker Capactor (plug and play) Basically same as the capacaitor I installed, but has resistors also to emulate a 55w system as if you were running stock halogens to prevent CANBUS error messages on equipped vehicles.

Wish me luck, anybody with any insight please chime in.

Alright got the anti-flicker devices insatalled,the HIDS work perfectly now, i threw out the capacitor it did nothing for me. Every now and then the left side doesnt turn on but a simple off-then on cycle of the headlight switch and turns on instantly!
