1-Should I remove my hid kit before taking it to the dealer?
2-Is the TYC tailights plug and play? I need to take them off to put the stocks back on...

Thanks

If you are selling your car, I would take your HIDs off because it will potentially hurt YOUR resale value, and raise THEIR resale value. You will lose money.

If you are just taking it in for a tune up/oil change, I worried about that when I first started to mod, and no, you will be just fine, I go in with header and everything, no problems.

To my knowledge, TYC taillights are direct replacements.

Thanks. Just changed the lights and they are direct replacements.
As for the HID kit, won't they keep a log of it and later on if I ever had electrical issues they could say that it was due to the kit?
