Does this have a BA15S base and is the bulb equilivant to an 1156?

Yes this has a BAU15s base. A 1156 bulb has little tabs on the base that are 180° apart, or exactly opposite each other. This bulb which is a 7507, has those tabs 150° apart. If you file down one of the tabs then you can use the bulb in either type of socket. The tabs don't do anything other than help hold it in place and it'll still be snug and work even if one has been sanded down a bit.

We searched for replacement bulbs for my son's 2021 Hyundai Elantra for days. These actually fit!! Nothing else we tried did. The nubs on the side are offset and not 180° apart like 99% of bulbs are. NOONE local had these. No auto parts or walmart, nobody but the dealer and we weren't paying 19 bucks for 2 bulbs. Anyway..these actually fit!

Make sure when replacing to check ALL the contact points and surrounding electrical conduit. For some reason after replacing, I still had NO turn signal, ask my local Porsche independent service provider and he guided me toward this solution. A small amount of corrosion in this area ( looks like rust ) was simply scraped off and all was good.
