I didn't like how dim my Depo side markers were in comparison to the rest of my light upgrades, so I modified my front side markers to make them switchback & brighter.
Now they have 12-13 white and 12-13 amber Led's that are visible vs. the dinky 2 Depo put in.

I'm going to do the same to the rear but I'm leaving them red and they will blink red to match the rear led turn signals I put in.
I would upload the videos but I'm not sure how to here .

 

What did you put in the sidemarkers?

 

Some cuttable led switchbacks I got from Amazon. Not sure if I can post the link?

I just did the rear today, I'll have pics up in a bit
