The Edge Tail Light Kit is one of the most popular upgrades for the WR250R (and WR250X). It replaces the big ugly stock tail light/turn signal assembly and gives the bike a much cleaner look. While the Edge Tail Light is pretty bright, I've always thought it could be brighter to help drivers see me a little better when approaching from behind.
12oclockLabs has come to the rescue with their DRC Edge2 Processor Upgrade Board (shown above), which is a drop-in replacement for the OEM LED board inside the standard DRC Edge Tail Light. Not only does it make the tail light and brake light brighter, but it also has features like safety brake pulsing and the ability to flash integrated turn signals (if you decide not to run external turn signals). The unit is also designed with 500,000 life hour capacitors for an exceptionally long operating life.
From a safety standpoint, I think the brighter tail light/brake light and safety brake pulsing (brake light flashes a few times when you apply the brakes) are reason enough to install this mod. I've already installed it on my WR250R and will be adding one to the WR250X as well.
