Hey Gang, here's a quick guide on installing the M1 Universal Brake Light Flasher / Modulator. This is the second unit I've installed (first on a LX150, this one on a GTS 300) and I'm very pleased with the functionality and ease of installation.

Scooterwest sells the lower-end model of this unit for $27, which isn't programmable. The M1 will run you about $20 and is easy to program.

Amazon link to purchase: Amazon Link: https://www.amazon.com/Vehicle-Flasher-Module-Universal-Motorcycles/dp/B00FADDOL4/ref=cm_cr_arp_d_product_top?ie=UTF8

Installation is a breeze and should take less than 20 minutes including programming.

1. Remove your brake light from the scooter housing. The LX had two phillip head screws. The GTS has a single T25 screw.

2. Cut the black wire with white stripe about midway and attach the included electrical connectors. Use some dielectric grease to prevent corrosion. Ignore the yellow wires (running lights).

3. Connect the included T-Lok connector to the black wire (ground). Again, use some dielectric grease to prevent corrosion. Connect the black wire from the modulator to the T-Lok connector.

4. Connect the red wire from the modulator to the black/white wire going to the harness.

5. Connect the yellow wire from the modulator to the black/white wire going to the bulb.

6. The blue and white wires are used for programming.

I programmed mine with 15 fast flashes, repeating every 6 seconds the brakes are engaged. See video for final result.

Programming:

See below picture for the programming instructions.

My unit appears to have two additional steps (#2 and #3) that weren't included in the original instructions. See below for the steps that worked for me:

Step 1:Flashing mode
1 - Standard
2 - Fast flashing followed by slow flashing.
3 - Continues change of flashing rate from high to slow

Step 2: Deactivation timeout(i.e. If mode 2 is selected and brakes are released and pressed before 3 seconds it will not flash. It will be a solid light)
1-No timeout
2 - 3seconds
3 - 5seconds
4 - 10seconds
5 - 20seconds
6 - Dynamic Timeout(extends timeout from 3/5/10/20/40 seconds every time brakes are depressed before timer expires)

Step 3: Light off intensity(brightness of light between flashes)

Step 4: number of flashes 1-16

Step 5: flashing rate (fast to slow)

Step 6: continuous mode
1 - Repeat after 6 sec
2 - Repeat after 12 sec
3 - Repeat after 18 sec
4 - Repeat after 24 sec
5 - Continuous mode disabled
6 - Constant flashing. No solid brake light

This looks great. I will try it. By now, the Amazon link goes to M2. I'd also like to look at headlight modulators. Dis you try one of those as well?

I am trying to follow the well-written instructions but my Vespa GTS SuperTech 300 HPE has different wiring harness for the taillight. I have 3 wires on my Vespa not the four on this post. I think they may have changed this starting with the 2020 model. Lucky me!

I have put together a diagram that I think will help in explaining my situation. I am not a handyman when it comes to electrical things, but I should be able to figure this out. I have the exact same modulator as the original poster, but am getting stumped in determining how to connect all the wires. If someone can take a look at the digram and explain shat needs to be connected to what I would very much appreciate it. Let me know if there's any other info that I can provide which would help in getting some guidance--for example I have the OEM wiring diagram (if that would help) which, BTW, I can't read/comprehend.

The original poster in step #2, talks about about a "black wire w/white stripe" which I don't have, because as mentioned above the 2020 must have changed the taillight wiring. I think that's my source or confusion. Please help!
