The very small light systems in this category have a so called constant current source as for each output. LEDs can be connected directly. As a specialty, no series resistors are needed! The LED's anode is directly connected with the main battery's plus terminal.

The output current amounts to approx. 20mA, which is absolutely enough for LEDs in small models. For the controlling of lighting boards we recommend the more powerful modules ML4 and MM4.

For UL4 or UM4 only one free joystick channel or a button/switch with three positions is needed in your radio.

UL4 micro light system

The micro light system UL4 provides four switch outputs for indicator, breakdown indicator, parking light, and driving light. The module is the perfect match with a speed controller S10.

UM4 micro Multiswitch

The micro Multiswitch UM4 is a universal channel expansion for function models. One possible application is e.g. the supplement of flasher, high beam, fog lamps and roof lights.
