Anybody try using Led head lamp conversion kit on their Trax if so what did you have to do just swap bulbs or add a resistor for the CanBus system. Thanks

When switching to LED you have to do your homework. Some LED headlights draw MORE power than the stock bulb does. In newer cars they use the thinnest wire possible to save weight and cost. You have to be sure that the bulbs you want to use will not melt wires, connectors, switches or computer modules.

The next big issue is that your headlight lens and reflector were designed for the halogen bulb which puts out light in a full 360° sphere. LEDs are directional and the focus of the beam will not be correct. This is part of the reason that you see so many cars on the road with blinding headlights. Instead of a properly focused beam, light is being scattered everywhere and the cutoff that keeps you from blinding other traffic is no longer there. The other part of the problem is that most people do not reaim the headlights and have low beams aimed as high or even higher than the the hi beam is supposed to be, again adding to the blinding of other drivers. I have done many conversions to LED and HID, I have yet to see one that did not have to have the aim turned down.
Before you start the conversion park the car about 30 feet from a wall, mark the spot on the ground where all 4 tires are located, next turn on the headlights lo beam and mark on the wall where the top of the bright area is. When you do the conversion you need to adjust the aim to get the top of the bright area back down to where it was with the stock bulbs.

As far as the CanBus, Some LEDs have the CanBus built in, some you can order the CanBus adapter with the bulb, and some just leave you on your own. Again you have to do your homework.
