20PCS T5 LED Lights for Car Dashboard, Super Bright 3030-3SMD Auto Bulb with Twist Lock Socket, Interior Instrument Panel Gauge Indicator Replacement, Car Accessories (Blue)

The bulbs themselves where easy enough to install, but were not as bright as advertised. Also out of the 20 I had about 6 that were not functional. The dimness may have been to my instrument cluster itself, as it was a Ford and they have a greenish film on the instrument cluster itself. I believe most car manufacturers do this as it is cheaper to use normal white bulbs and tint the glass/plastic instead, so if you REALLY want these to function as they should, you'll most likely have to replace that part of your instrument cluster with an aftermarket clear one. The twist knobs did not fit my truck ('08 F150) even though Amazon said they would. Not a reflection on the product, just letting potential customers know.

Amazon needs to change their compatibility chart. It’s not compatible with a 2004 Corolla. The ones that are they have advertised as not..
