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

LEDs
Electrical tape

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.
