Amazing
Proper, old-school bulbs that just work. No drama, no error lights, no flickering like a haunted house. Swapped them in and my indicators lit up like they’d had a motivational speech. Bright, clean, and built like Bosch actually cares about making things that last longer than my patience on the M1. Perfect little upgrade for any car that’s sick of cheap bulbs blowing every five minutes.

Just what i needed
I purchased these before but only needed to replace the 1 bulb it lasted about a year then recently had both front daytime running light bulbs give out on me i'm guessing it wasn't an issue with the bulbs as both blew. so i purchased this pack (again), nice a bright bulbs again at a reasonable price. Arrived quickly, The only issue is fitting them properly. It's not an issue with the bulbs but my big clumsy hands. these are compatible with my 2014 VW T5.

Neutral Colour Temperature
Top quality truly long life bulb produces a pleasant neutral temperature light exactly the same as if not better than other OEM brands

Good
Bought the wrong size but completely my fault. Amazon asks you to put your reg in and tells you if it will fit your car or not but I didn’t use it. Probably should have. Great replacement bulb if it actually compatable for your car though. It is white so can be used for headlights of similar I assume.

Wrong bulb advised.
Just to make others aware. These aren’t the correct bulbs for a 2012 Santa Fe P21/5W are the correct socket versions with double filament for the brake & tail lighting. Hope this helps some folk.
