I wanted a modulator to flash my brake lights before going solid red for higher visibility when stopping. I like the fine tuning of the delay between flashes

Advantages: Plugs into OEM harness, no splicing. Easy upgrade.

Disadvantages: I wish the modulator was a smaller so it could fit under the bracket for the seat lock. I had to bring the modulator forward towards the battery and displace the turn signal modulator to give it a home. Otherwise my review would have been 5 stars.

This customer purchased the item at our site.
Easy install, works well, unit is a little bulky

Advantages: Easy to install, makes me feel safer now that my brake light is a lot more eye catching for drivers behind me.
No cutting wires, included harness adapter works great.

Disadvantages: Modulator unit is a little big, making placement of it in the tiny amount of space under my XSR900 seat a little awkward, but it does fit.

Advantages: Plug and play.

Disadvantages: None!
