i have a 2007 bmw 525xi with halogen lights and switched to the 2008 LCI xenon convert.my xenon lights turn on but as soon as i start up the car my lights flicker constent.Any help would be great thanks

 

Its not as simple as swapping over the lights, the car needs to be coded for :-

SA522 Xenon lights

and if they are adaptive then also :-

SA524 Adaptive xenon lights.

I would stop using them until u get the car coded, as the constant on/off will kill the xenon bulbs.

 

Yup as BLooD said above!

Coded the right way 'cuz your car don't have the Xenon option when it was born and both the headlight & the car expecting one thing but got different thing. After that you may run into warning(s) pop up about the parking light and/or hi-beam if it's not coded properly.

Or if you can not code it you can mod the Xenon to use capacitor ... there are plenty of threads about that if you search around.

BTW to the forum!
