has anyone heard of or had experience with this brand? Our Tahoe came with an HID kit installed when we bought it but the driver side light only works 1/2 the time so I want to replace it all with a good kit. A local car audio shop sells this brand and will install for $250 total with a "lifetime" guarantee.
I really do not have time to mess with getting a kit and installing myself for the next few weeks and we need the headlights to work so that is why I was going to go to a shop.
thank you for any input

 

Does the existing HID have a relay harness installed?

Check with supporting vendors for this site. If there are none, try DDM Tuning. I purchased a set for ~$75 and installed in ~2 hours. To do it properly, you need to reach the third bolt through the wheel well (driver side). Other have just removed the upper two bolts and slid the housing out. I have no idea how they fit their hands in there to do it properly though. The passenger side, you can access by removing the air filter box.

 

how would I tell if a relay harness is installed? the ballasts are mounted vertically on a bracket and there are just the 2 wire/connectors on the bottom coming out.
if I move one of the wires on the driver's side ballast just a little the light will come on and stay on, but if I turn the truck off then back on it won't fire up unless I mess with the wire.
the ballast makes a noise - kind of like when a flourescent light is starting to go out, a buzzing noise. I would assume either the connection is bad or the ballast is bad

 

If there is a relay harness then the lights will be directly connected to the battery for power.

With you jiggling the wires and it fires up, it seems like it is a wiring issue. If you can not fix the wire yourself, it is cheap just to get a new HID kit.
