My puris C does not come with led headlights like the newer models. I added a led strip and have good results.
Step 1: Materials
You only need 2 things
I got the LEDs from here
Step 2: Install Leds
I buy 2 strips of white LEDs from eBay.
I take off the small marker light bulb. I plug the led wires in into the marker socket and test it. It works so I use the tape provided with LEDs to stick it on the headlights. This should work with all vehicles because market lights is 12v.
