Quickie lighting system with turn signals and brake light from (mostly) scrap/on hand parts
Step One: collect the needed parts
MR-16 LED lights
LED turn signal flasher
2x LED side marker lights
LED Stop/Tail light
2x lever switches
spdt-center-off toggle switch
12v NiCd battery
Step 1: Brake switches
Mount lever switches front and rear and link to brakes so switch closes when brake operates. Wire switches in parallel. I used switches with rollers and tied braided dacron fish line to the roller and to the brake cable (with a 'taught-line hitch' at one end to allow adjustment) - switches could also be mounted so that caliper movement operates levers...
Step 2: Brake/Tail Light
Light can be either a bright red led light for brakes plus a dimmer red led tail light, or a combo brake/tail led light.
(edit: pictured combo light just arrived from China - !@#$ wires enter from top *WITH NO SEAL* so rainwater can enter and turn the $7.50 blinky tail/brake light into a useless P.O.S. if it isn't sealed up before installation)
Step 3: Turn signal lights
Turn signal lights may be either amber led side markers (truck/trailer side markers can be found in most any auto parts store) or motorcycle turn signal lights.
