Just took a few pics of the sequential turn signals I installed a couple weeks ago. Sorry about the quality of them, but, you should get the idea. I got them from Custom Dynamics. Whatcha think?

On the 1st gen instrument cluster there is a reed switch mounted above the speedometer cable input. This reed switch senses the turning of the front wheel and outputs a signal to the cruise control & turn signal cancel circuit. Picture attached below. Does anyone know if this reed switch pulses 1 time per revolution of the speedometer cable or a different number? I don't have a spare cluster head to check for this, and don't want to dig into the one on the bike. I am working on a digital circuit to replace the flasher/hazard relays and the turn signal cancel circuit. I will use the count output by this reed switch to determine the distance the bike has traveled and use this input to cancel the turn signals at some distance traveled point. I know the front wheel circumference and the number of revolutions the cable makes per wheel rotation. With this info and knowing the number of times per cable revolution the reed switch pulses, I can calculate distance traveled. I am going to replace the bulb in the rear turn signal housing with 15 LED's arranged in a pattern that can produce five independent arrows circuits of 3 LED's each. Second picture below. These five arrow patterns will be sequenced to give the appearance of a moving banner in the direction of the turn. At this point I plan to light first the inboard arrow, then at about 1/5 second intervals light the next arrow until all five arrows are lit, then turn off the first arrow, then each of the other arrows at the same 1/5 second interval, until all are off. This will give a full sequence every 2 seconds. This sequencing will be repeated as long as the turn signal switch request is on, or the self timer cancels signals. Also, there will be a brake light circuit that will activate all the LED's steady in both turn signals when the brake is activated. If a left or right turn signal or hazards are activated, the brake light for the corresponding side in the turn signal housing, or both in case of hazards, will be deactivated allowing the side to flash. Center brake light will function as it does now. If I have room in the turn signal housing, I will also mount lower wattage LED's for tail light function. I have an analog (relay) circuit designed that will do the sequencing and brake functions using the existing outputs from the turn, hazard & brake switches. I will convert that design to a digital version which will be fairly compact and low power consumption. I am estimating about the size of a cigarette pack. This controller will also control front signals and dash indicators without the sequencing or brake light features. Gary -
Well I finally got my rear sequential LED turn signals installed and working properly. I had them done last year but never got around to getting them put in until this week. Now I just have to get the fronts done. What do ya think? Thanks, Bill
