Yes I have , have a old electric car I put them in , works well , got it from a on line store called Super Bright Leds , also got the 194 led bulb replacement for my side marker lites on my pinto ,

They put out a good white light , I work on aircraft and now most of the newer aircraft have LED landing lights , worked on a brand new jet last week and it had every light LED , no bulbs ,  also if you use leds for the front and rear lights turn signals you have to use a electronic flasher , Napa has them ,
