Description
Description. JUST RIGHT: Yes, we know. We know. You have been looking for a third brake light upgrade for a while now, only to retreat every time. Discouraged when the search returns no more than the same old variety of el-cheapo options out there. The X3B from Morimoto is different though. It's the one you've been waiting for. It's a no-compromise brake and bed light that offers the perfect pairing of style, performance, and utility, and it's now available for a wide range of today's most popular trucks.
RAPID FLASHER: This module can be added to your X3B brake light setup to automatically pulse the brake light optics 3x before staying on when you step on the brake pedal. Though the standard optics and powerful 3W LEDs in the X3B brake lights are already highly visible day and night, the addition of this module makes sure that followers will notice when you step on the brakes. This feature has become standard on many of the most modern trucks and cars.
PLUG N PLAY: The X3B Rapid Flash module is 100% plug n play with the Morimoto X3B brake lights and can be connected in seconds. For use with for the X3B Third Brake Light only, It is not compatible with other aftermarket products or OEM units.
Warranty. 5 Years

Good feature to have
In order to use this product obviously you have to get the morimoto 3rd brake light. The difference between not having it installed vs having it is good. I have noticed a lot more vehicles behind me slow down quicker. Not hard to install at all.

Be Different!
Ordered this along with a X3B Third Brake Light kit since I wanted to add the 3 flash then solid operation. Item seems well built, connectors and harnesses of good quality, has the same type of OEM fabric tape so it matches, and looks factory. Comes with a 3M adhesive tab already placed. On my Ram found that the only place I could put it so it didn't interfere with the X3B is tucked up on the underside of the roof near the third brake light hole. Cleaned that area with an alcohol prep pad, let dry, then peeled protective backing off of adhesive strip and pressed into place. After a few minutes, finished connecting all the connectors and the install of the X3B. With a test, functions as described! Flashes the third brake lights (which are bright on the X3B!) three times before it goes solid. Definitely will help attract a driver behind you especially in this day and age when everyone seems to be on their dang phones. I recommend this if you want to be "different", although newer cars on the roads do have the 3 flash to solid as standard operation of their third brake lights

Simple product easy to install gives that extra bit of safety. On the road today you need all the help you can get to assure other drivers see you. This product helps with that. If you are on the fence to add it or not just go for it.

Rapid flash
If you're getting the morimoto 3rd brake light this is a must. The light itself is super bright and with this module it flashes 3 times everytime you hit the brakes. If those distracted drivers don't notice this then I don't know what they're doing.

Module working good
It’s a little tricky for me to get into the lining, but the installation wasn’t hard. I love the flashing of my third brake light!
