LED Rear Turn Signal Question

So yeah. Fast blinking because of low resistance and all that. But here's the weird part.

So, I was given four 7443 LED bulbs. Into the tail light they go. I thought maybe the CANBUS would be smart enough to figure it out and low and behold. Signals blink normally, until I turn on the heaights, then the rapid blinking thing.

So I guess this has me wondering are there LED bulbs that do work in the rear as turn signals?

 

I believe this is what you're looking for. They're pricey, but very well made and you can also order plug and play modular resistors.
