The energy-efficient bulb operates within a wide 9-14.8V DC range and is designed to last 30,000 hours on your motorhome or boat—25 times longer than incandescents.

Important Notes - Please read before purchasing:
  1. 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
  2. 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.

Fits 2011 Mustang Reverse Lights

Just in case there are any Mustang owners are looking, this fits the 2010-2012 Mustang tail-lights. Just pull back the carpeting in the trunk and remove 3 nuts, then plug and play. I'd like to see a little brighter option (and maybe there is?). They look great, but don't expect better than stock brightness for backing out into a dark area.

Indy Ford

Great fit & color. They look good & function well in the rear cargo light of my F-150. It was amazing how scorched the bulb housing was from the heat of the OEM Incandescent bulbs.

Not bright enough

I ordered these in amber to replace turn signal flashers (behind an amber lens). These are only about half as bright as the incandescent bulb. No good.

For a brighter alternative, we suggest the WLED-AHP5

Great lights

These lights are awesome. Much brighter than the bulb they replaced, great in Cool White. After installing, there was a period of time needed to get used to them. Very nice products.

Unfortunately, one of the two bulbs started acting up after about 2 years. Sometimes, a light tap on the housing would make it start working again but just recently, it stopped. I took out the bulb to example and the connection from prong to resistor had broken. I'm certain it would be an easy fix if I could access it. I do plan on ordering a replacement if I cannot manage to fix it myself.

Still, absolutely great product. I've received lots of compliments since installation.

Great product! Used as license plate lights on my '12 Ram 1500 Sport and man are they bright! Also give it a more modern, sleek look compared to halogen lights.
