GTC Head and Rear lights question ?

[tucpal]

You can change the LED DRL on the GTC without adding any load resistors as they are not monitored on the canbus
these are good and work fine they will dim down etc

the hid kits from HIS DIRECT work on the GTC also there have been many that have done that and no problems reported

the rear LED tail lights and interior you need the LED,S i pointed out in this post
i don't think GTC owners will get any errors from the tail lights as the canbus monitors the drl and tail lights in one go
so if the drl are not monaterd the tail lights should also not be ether

so just to be sure buy 3 packs 6 bulbs if you get errors on the tail lights then you can use the bulbs
in the inside courtesy lights then you have not wasted any money
read the whole post you will find the newer version in there with links to bulbs

as for the rear indicator and rear brake lights a load resistor would have to be done to stop error messages
but they really are not needed they are bright as they are.
