Great bulbs for the money. There are many alternatives to choose from of varying quality. Didn’t want to wait for a couple bulbs by snail mail from Superbright. Bulbs work great , operate at a low temperature and are brighter than some other bulbs with more actual LED’s. Also a couple pointers , these bulbs don’t automatically switch polarity. Also if you’re signals flash quickly then I recommend a proper relay for the flasher to accommodate the low resistance from an LED type bulb. Love the way these look and the consistent crisp light output.
