What are these relays for?

GeeWhiz · 05-04-2017, 11:26 AM

I recently purchased a 2008 E90 335i. Upon installing a JB4, I noticed two large black relays spliced into a power wire close the DME that runs into each of the headlights. What are these relays for? I have disconnected the power wire and noticed no changes to the headlights. Any ideas? I haven't pulled the headlights apart to investigate further. I was hoping somebody might have some ideas before I went that far. Any help is appreciated.

Someone installed aftermarket headlights and went back to stock?

Maybe a harness to run the angel eyes as DRLs

That's what it sounds like. I have the Daeos harness and it's very similar to what OP is describing.
