I used this when I upgraded my 2007 Classic to LED's

It lists the 4114 for the DRL but 3157 is compatible and that's what I used.

This is with the stock head light assembly though. I am not sure how you would wire it if switching to after market head lights. I would ask the manufacturer

I looked at the after market route but I am happy with the stock assembly and all LED's and this mod. Nice and bright at night with lows, highs and fog lights on at the same time.

Not certain I follow the suggestion to remove fuse. My truck is 2007 C5500. I recently replaced all 4 of the halogen sealed beam headlights with 4 after market LED sealed beam headlights. Now the DRL indicator is lit up (green) as usual, but the headlights do not provide DRL light. Are you saying if I remove the DRL fuse that I will then have DRL light from my LED sealed beam headlights?

Sorry I may not have understood your post before. I have LED lights that DO NOT have the DRL feature. So they wont burnout running lower voltage ( so Im told) Just pulled the #15 fuse. On my dash the DRL indicator light is on showing they are lit but no power goes to lamps.
