looking to upgrade all the exterior lights to LED on the car. Also know that I need resisters in place to do it as well. Looking to see what two wires/colors are involved in running the tail lights on a 2008 Volvo xc70 for both sides.

Has anyone done this with there vehicles?

Looking forward to the input here. Thanks.

All my exterior lights are LED in my 95 850 are LED, Plus the interior
courtesy lights. I needed no resistors, But I did need to modify the bulb out
sensors which are really not needed with LEDs that are more reliable.

I found the replacement LED's at dx.com very reasonably priced, but some
of the options are much better than others. The LEDs outperform old filament
bulbs in every way! More Light, Less current/heat, a break for the alternator
brushes.

It is a different set up for the newer cars.
I did LED in the back and I get Hyperflash. Some cars will have a light relay that needs to be upgraded to handle the conversion of LED lights. The relay module on this particular car is designed into the turn signal stem attached to the steering column. No way of changing that out since there is no replacement for it. Have been told by the LED mfgs that my car will need the resistors in order to work and trick the system.

What value resistors are they suggesting ?

I just got a batch of them for the car.

50w 6RJ LED Resistors

50 watt resistors ?
what's the value in Ohms
how physically big are the resistors.
