Hi guys,

running gradually out of farkle ideas I thought that why not make a flasher / modulator for my Hella FF aux high beams. This would be just for the occasional lane splittings as I would need to draw the attention of the bull headed half blind drivers in front of me. I don't want to use the 4-way emergency flashers as I would be drawing the unnecessary attention from the behind also.

The head light modulators as such are not allowed over here and some units that I have seen on the web are designed to be connected right behind the headlight bulb.

I would need a separate unit to command two 55 W halogen bulbs. Is there any rocket science in those units? I was thinking of building one out of a regular turn signal flasher relay that would be commanding a heavy duty 70 amp relay feeding the lights as I am afraid the turn signal flasher would perhaps not tolerate the 110 W halogen load. I happen to have one extra switch (the last one of my 18 extra switches :p ) available for commanding the turn signal flasher relay. Whaddya say, would this work?

Regards

I'll bet one of these would work. We sell lots of them at our shop. They have a contact link if you need technical help.

There is no magic to them, and there are purchaseable units available which are wire in.

The law here in the USA is that the modulated light cannot be modulated from on to off, but only to a reduced light level, and at a specified frequency. The specifics are in an available federal document, which I have on my computer but it is too large to paste. If you are interested, I could find the section and post the relevant portion. However, since it is not legal in your country it is pretty much a moot point, and you could just use a timer and relay. If I was you, I would just purchase a "wire in" unit from one of the suppliers here and use it. It is easier on the bulbs to use one of the US legal modulators than to develop an on/off flasher. However, as you stated, just using a turn signal flasher to drive a relay capable of the higher current would be very easy to do.

PS: If you were to purchase a modulator for a Gold Wing, it is already capable of driving two headlight bulbs.

Would this (http://www.galls.com/style.html?style=FS039&assort=general_catalog) or something simular not do what your are after?
