new kellerman signals

am in process of converting to the kellerman 1000 mini halogen turn signals... a little bit of a pain in the butt due to finding out half way through that they need load resistors... but a question... due to the size of the resistors... am trying to hide them best a possible on the underside above the rear tire... pretty much the same area as the wiring... thinking of using an adhesive type glue... to fasten on the plastic surface... am aware that the resistor generates some heat... how much heat are we talking about?

Replace signal relay with an electronic LED friendly one. Resistors are only needed with original relay which is ment for filament bulbs.

these are halogen... not led

Electronic relay should still fix the issue. Normal relay needs resistance in order to fire. Electronic relay blinks away no matter what the resistance on the wires is.

am I correct that the original relay (factory) is for filament type bulbs?

Yes. It needs the certain resistance to work.

No harm in trying, unless the Kellermann instructions specificly call for the resistors to be in place. Eg. the Kellermanns burn too bright & hot without them.

considering that kellerman info is typically in german... leaves this ignorant english/espanol speaking norte americano in the dark

These guys seem to recommend electronic relay with the Kellermanns, so it should work OK:

Slight correction: standard relay does not require resistance to flash normally, it requires current through bulb to be high enough to indicate good bulb. Because LEDs have very low current requirement, it senses this and flashes fast to signal burned bulb. To remedy this you need to add another electric path to increase current through relay - low value resistor parallel to LED bulb, so more current flows through it then through lamp itself.
These halogen bulbs also are rated for only 0.5A (standard bulb is more like 2A), so need parallel resistor to draw more current and fool relay. You can use electronic flasher like for LEDs - it blinks at constant rate regardless of current flowing through it.

thanks... finished the job... lot of soder and tape... but it works great
