LM Input Signals

LM Input Signals

Input signals to the lighting module are from the following switches:
- Park/low-beam light switch
- High-beam/headlight flash switch
- Turn signal switch
- Fog light switch
- Hazard switch
- Brake light switch
- Dimmer control

These inputs are ground switched except for the brake light switch.







Brake Light Switch - Brake light switch is now a hall-effect transmitter with three connections. The first connection is power, supplied from KL R, with the second being ground. The third connection is the signal wire to the LM.

The electronic brake light switch eliminates the need for the brake test switch. If the brake switch or it's circuits fail, the brake lights will be permanently on from KL R.

Dimmer - The LM control KL 58g (instrument cluster, LCD, and switch back lighting). By using a pulse-width modulated power supply, dimming commands are input to the LM by way of a potentiometer wired to ground.

Light switch illumination - A separate circuit is used to back light the symbol of the light switch. The symbols are fully illuminated when KL R is switched on and the lights are off. After the lights have been turned on, the switch back lighting is reduced to the same intensity as KL 58g.
