Greetings

Can anyone recommend a good after market replacement for the stock Hodaka turn signals? I'm looking for signals that are smaller and will last for a good while without falling apart.

Thanks

Tom

I would look for something along this line. Should have a broad range of voltage input and very low load demand.

You will probably find that the LED signals will not flash when installed on a Hodaka. This is because the old Hodaka flasher is not designed to work with LEDs. You will need to purchase a LED flasher, but I am not sure if they are available for 6 volt systems.

Most LED fixtures work from 9V to 36V. That's pretty close to what a Hodaka puts out. Easy enough to try with any 12V LED lamp which are becoming more common in most auto parts or RV parts stores.

The flasher is likely a bimetallic type. Current from the signal bulbs flows through the flasher bimetallic element causing it to heat up and bend, thus opening the circuit. When it cools, it goes back to its original shape thus closing the circuit. This is what causes the lights to flash. LEDs have a much lower current, which is insufficient to heat the bimetallic element in the flasher. Result: no flashing.

Electronic flashers for LEDs are available at the auto parts store. I have been using them for many years even without LED lights because they are more regular in their flash rate, independent of load.

To confirm, are you successfully using a 12V LED flasher with 6V incandescent bulbs?

For what it's worth, my 250SL signals (6V incandescent) were hyper flashing when the revs were up. Replacing the original flasher with a NOS flasher from SH fixed it.

Given the same brightness, a 6V bulb will draw twice the current of a 12V bulb. With the higher current, I suspect that a 12V flasher will cause the hyper flashing.

I am not sure how common 6V electronic flashers and LED lights are, but they may be available (I'm too lazy to search).
