Just to be sure - you have used these?Why not just drop in a 3 flash LED 1157 brake light bulb? Two for $18:
When you hit the brakes, it flashes 3 times then goes solid.
70bones,1157 bulbs won't work in a newer 'strom, as they have LED tail / brake lights. If you want it to flash, you have to install an LED flasher, which is different from a "normal" flasher.
What kind of connectors? Posi-Taps/Loc's are awesome...quick and easy:70bones,
Did you have to remove most of the arse end plastics to get it done?
I bought a plug and play flasher unit with connectors and my manual shows I have to remove a lot of stuff to get to the rear light connector.
