  • Headlight "Flash" feature

    O.K. Am I allowed to ask a really dumb question?
    Is my '76 TR6 supposed to have a temporary high beam or "Flash to pass" feature? My '69 TR6 (years ago) had a foot switch for toggling between high and low beams. My '76 has a steering-column mounted high/low switch, and I can pull it forward slightly but nothing happens. With the dashboard headlight switch on, the lever works to switch back and forth from high to low beams. Am I supposed to be able to flash my headlights with this switch?
    Thanks for letting me ask a very basic question!

    Try pulling it rearward. If that does nothing then it probably is not a feature.

    My TR4 flash to pass worked by pulling the headlight stalk rearwards.
    I never drove the '72 TR6 at night, so don't know about that one.

    Also, if you have an owner's manual features should be listed there-in.

      When I replaced the wiring harness in my TR250, the new harness did not have the wire for the flash to pass feature. I took the wire out of the old harness and added it to the new harness. It now works for flash to pass.

        My 74 has flash to pass on the steering column. Interesting thing is that power for the flash comes from a different circuit than hi beams. Wonder what the rationale for that was.

        For just a little more, you can do it yourself!

          It could be redundancy in case a brown wire came loose or a partial column switch failure. The pass to pass contacts are independent of the main switch function of both the early and late column switch.

          On all models other than the TR250, when using the flash to pass it is possible to illuminate both the low and high beams simultaneously and I suppose that could overload the wiring. On the TR250, whichever beam is selected with the dimmer switch is what you get with the pass to flash.

              Thanks for everyone's response. The instruction manual that came with the car does not mention it. However, the wiring diagram in my Dan Master's book clearly show the wiring for it---and my harness is original. When I pull the "high/low" switch rearward (toward the driver, I can feel a definite give. So, I think I have a wiring problem , probably at the steering column near the ignition switch. I will investigate next time I'm behind the dash. Thanks again!

                Ocularsharp --- The flash to pass feature on my '73 quit working on my '73 about 10 years ago. With the cover removed, I found that a quick blast of WD-40 into the switch mechanism and a few wiggles and it started working again. I mention this as it's easy to do when nothing's broken or missing. Dick

                You learn something every day!!

                I've owned my 75 (which is actually more like a 74), since 1989 and I did not know that it had such a feature.

                I gingerly gave it a try the other day and what do you know, it does have the "flash to pass" feature.

                I'm in awe.
