Controller Features are below.  Currently, there are 2 versions.  Both have 4 inputs.  One has 5 outputs for blinker and brake light control.  The other has 8 outputs and can be expanded with up to 6 more.

• Takes the place of standard blinker relay, allowing custom blink rate, complete with blink clicking
• Programmable signal controller
• Signal lights can be set to run dim as running lights
• Brake light can be set to blink with signal lights as an integrated signal/brake light
• Front lights can be set as fog lights, i.e., they're running bright and dim when blinked
• Rear turn signals can be set to strobe several times when brake is applied, and can also be set to strobe periodically while brakes are applied
• Rear turn signals can double as extended brake lights
• Rear brake light can also be set to flash or strobe periodically when brakes are applied
• All signal lights can be set to strobe when horn is honked
• Custom features as the customer requests!  This thing is programmable!

Brake light (Note: Actual product may vary slightly.)

• Total of 34 LEDs
• 16 LEDs on each half of brake light, on two separate circuits, enabling brake light to double as turn signal, totaling 32 LEDs
• 3 LEDs on each side to give better side visibility
• 2 bright white LEDs aimed down for license plate lighting
• Minor modification of brake light assembly and wiring harness done to owner's hardware

Turn signals

• 8, 12, or 16 LEDs in several arrangement choices
• Optional 4 superbright LEDs, with more light output than 12 LEDs
• Minor modification of the signal assembly done to owner's hardware
