Important Notes - Please read before purchasing:
  1. Your vehicle may require an LED compatible Flasher or Load Resistor. LED brake/tail lamps will not flash with most stock flasher units due to their extremely low current draw. Try our Vehicle LED Bulb Finder to find a compatible flasher for your vehicle. Please See More LED Car Bulb Notes
  2. This bulb is oversize, please see dimensions under Specifications tab.
  3. For best results the LED color should be the same as the lens color. If bulb is behind a clear lens, use the appropriate color for turn and brake light functions. Please See More LED Car Bulb Notes
  4. If your daytime running light application serves multiple purposes, this bulb will most likely not work for your vehicle.
  5. To protect LEDs in marine applications, it is advisable to use a 12 VDC line conditioner to compensate for voltage irregularities common in marine low-voltage systems.

Good quality, superb brightness.

These bulbs are at least 80-90% as bright as the stock incandescent, which is about as good as you can hope to ask for when talking about these applications. Using red bulbs in a red lensed housing, they actually appear slightly brighter than the stock (clear) bulbs because less light is lost passing through the filter. I bought them to use in conjunction with a brake light modulator, since the instant-on properties of LEDs allow you to flash them rapidly and make them more attention-grabbing. They have good spread and coverage so the whole housing lights up. If you need any brighter, get a whelen.

Only downside is the price. A full set of these will set you back a pretty penny.

Just about as bright as incandescent

I bought these for brake/marker lights on my 2012 Fusion. Compared to the O.E. lights, this has a slightly deeper shade of red, with light output so close to standard (both dim and bright modes) that it's hard to discern the difference, but I've come to the conclusion they're not quite as bright as stock. I could still be getting tricked by the difference in shade and apparent lack of a "hot spot" evident from the standard bulb on the reflector.

It's a light

I reviewed the 7440 version of these bulbs as well, and this is more or less the same. They are comparable in brightness to the original brake lights in my Honda Element. I can't speak to their durability over time as I haven't had them for that long, but I don't see anything that would indicate an early failure. I'd recommend them.

Great for motorcycles.

These work awesomely for freeing up some extra juice for accessories. Just remember to get an led flasher so they don’t hyper blink.
