LED gurus please step in

Ok so I just got my switchbacks and I'd like to know if I could safely paint or use a permanent black marker on the gaps between the LEDs so that the switchbacks wont be so noticeable in my headlight housings. Is this possible or will it cause the lights to overheat?

Somebody on here did this before so it should be fine I assume. Hopefully said person would have posted if he/she had problems down the road lol. But yeah, its been done before.

That's it, they are getting painted! If they get f'd up we will just buy new ones, whatev, they are not too expensive. Let me see if I need anything else painted hahaha

LED's do not give off heat (well that much) I'm sure it will be fine.

Yep go ahead and paint them, shouldn't be a problem. Only light coats should be required.

ok, so I will update this thread

we did end up painting the switchbacks, well 6spdtl-s did, I helped a little, very little actually. I am a better supervisor anyway hahaha
really though they look awesome, he did a great job!! I took a quick pic with my phone tonight so you guys could see.

Looks nice! I would have done that but I got the clear diffusers.

whoa.. what are you painting them with?.. just FYI.. some polymer paints conduct electricity as well as any paint with metallic content. I would even be wary of some acrylics & oil paints (impurities).. Even conductivity in small amounts can result in over driving the LED elements and burning them out. Just check the material content of the paint. If you want a sanity check.. do a continuity test of the paint (over paper / wood) or apply a voltage and try to obtain a reading.

I can't tell by the picture but it looks like you painted the SMD contacts but didn't paint across the connections, unless you painted it with pencil lead it should be fine this way whether or not there is metal content. Just don't cross the connection or apply too much, that's where resistivity can come into play.

As far as I know it wasnt a polymer....this was my concern when I first started this thread. On mine I did a few coats of standard spray paint and then used a coat of AM matched spray. No problems so far

Some spray paints (enamels) have a high percentage of titanium dioxide (used in some semiconductor processes) along with other metals and therefore are conductive. I wouldn't worry too much though.
