I checked out the Lasfit website and chatted with them. They recommended an amber version for my car, although Revain Your Garage said the red was the right one. Just take the time to chat with Lasfit. I'm assuming these bulbs have TWO circuits. I bought some pre-wired resistors for another set of 7443 LED bulbs to solve the hyperfash problem. You had two resistors connected to the same terminal. They are HUGE and I didn't think I could fit them into a fixture so I bought a Lasfit set. They work great in normal use. These lights will hyperflash if they blink for a LONG time. I haven't timed it yet but I'm guessing 2 or 3 or more minutes. It's a few signal cycles in my area. Until I get to the next signal they are fine and not blinking. I drive with the headlights on, which does NOT cause them to come on when I turn on my turn signals.
