Ok, my dad has a 2011 RX350 with out the Factory HID kit. I bought him an H11 6000K HID kit. My question is do the lexus vehicles require a Relay Kit to run the HID's or compassitors to prevent a bulb out signal like the BMW's

Thanks
Shawn

Anyone know the answer?

I think the best advice will be from the HID kit manufacturer. Did you get it from one of the CL vendors?

OP: is it a projector non HID or a Reflector halogen housing?

If its a Halogen Reflector housing then the HID's you will install will cause huge glaring issues.

If you bought from xenondepot or kb, then the plug and play kit you have has a relay on it, I've installed 3 of them with no problem
