Here's a video. Very easy. Get yourself the orange bulbs with the reflective coating on the outside. The one I installed doesn't have that. The orange bulb I have installed shows through the clear lens and it looks kinda like a fried egg. The reflective bulbs prevent that.

You have to disassemble the reflectors and remove the silver backing. Take off the orange covers on the factory units and then replace with the clear ones. It looks decent, though not perfect.

I just did mine last night:

It's really easy to get the orange lenses off the OEM assemblies. Getting the silver/plastic backing off the reflectors is much more difficult, but the silvery plastic is much softer than the lenses, so cut through them with a utility knife then pry the backs off the clear lenses. I used hobby grade CA glue to mount the clear lenses.



BTW, it's far cheaper doing it this way than buying replacement front orange markers in clear.
