    Hazard lights?

    One thing I've always wanted on my bikes is hazard lights. Basically, having all four turn signal lights flashing at once. Some newer bikes I've seen have 'em.

    This can't be a hard mod. All one would need to do, I would think, is just find a way to activate both turn signals simultaneously. I could add a switch to the handlebars - that's no problem.

    So... anybody ever done this? Got maybe a link to a site with a diagram or description? Ideas?

    I believe that BMW sells a kit for the airheads that will do what you want. It's probably a plug and play kit.

    The cheapest thing on a BMW is the nut that connects the handlebars to the seat.

    Hm. Nothing on the Sierra BMW site. You wouldn't happen to have a link, would you?

    I got the following part number from the ETK for a 82 R100RT.

    The diagram shows a switch, relay, diode, wiring harness and assorted mounting hardware.

    Thanks. I'll look into it.

    The BMW kit is best.

    It has the following feature, which you really need.

    Ignition must be on to activate 4-way flashers. It can then be turned off, and flashers will still work.

    Flashers cannot be activated with ignition off. (saves your battery from vandals)

    This requires a diode in the system.

    This is a kit that may become NLA. Check Motobins among others.

    I installed a switch that shorted the left and right turn signals together when I wanted four-way flashers. Did this on the R69S, 74 R90/6, 78 R100/7. Need to do it on the recently purchased 91 R100RT. Have never needed to replace a flasher.

    This sounds like exactly what I'm after. Can you elaborate? Does the switch go before or after the turn signal switch?

    I purchased the OEM BMW kit from Bob's BMW in Maryland three years ago and highly recommend it. It includes a diode, a second relay, wiring harness and instructions and is completely plug and play. On my RT there's even a blank hole in the relay board under the tank for the new relay. The switch replaces the blank in the center of the plastic handlebar cover -- all very slick.
