I was going through DRLS easily every 6 months.
Dealer lots noone could figure it out.
Most of thr time they would replace them.under the bulb warranty when we brought it for oil changes.
just got sick of it stopped caring..
forgot about all these great folks.
The polarity is causes the DRLS to blow. Because they need to be inserted a specific way.
The relays in the car is why. And the fuse system on the battery...
​ttery.cant explain it but know it to be true lol

Thanks for the brain jolt!
