GL1800 Top Trunk Spoiler Brake Light Modulator

Easy install, followed the directions, work great first time with no problems.

After remove 19 screws, plug 2 connectors and test the brake nothing happened, no brake light, nothing. Poor quality, 100% sure that they not test the product before delivery it to costumers. Very disappointed.

I ordered the trunk spoiler brake light modulator, I believe anything you can do to make yourself more visible is worth the money. I like the brake light modulator but had the same problem, it is wired wrong. I was excied to get it, plugged it in and nothing, traced the wires and discovered like another person the wiring is wrong. Changed it and it works as advertised.

I installed the spoiler brake light modulator just as the instructions said to do, but nothing happened. After pressing the brake pedal a couple of times, I smelled something hot. After further examination, I realized the wires in one of the plugs had been installed backwards. I switched them around, plugged it back together, & it works as advertised. A good safety item.

Does what it says. Plug and play. Took longer to get the trunk liner (and its dozen screws) out, than it did to install the modulator.

Great addition for the money.
