To this day I still can’t get the LED Turn signals to blink. I did get them to work last summer, but they quickly reverted to their non-blinky state soon after. I have no earthly clue as to why, but it doesn’t worry me. The first place I suspected that could be the root of the problem is the switch. I figured I’d poke around in there and try to simplify the already overcomplicated antiquated switching mechanism. Take a look, it’s weird.

I don’t think I ever really looked inside even when I was installing the clubmans.

Filthy. I suspect Honda used some kind of dialectic grease on the sliding mechanism and all sorts of dirt and grime collected in there for 35 years.

It really is a mechanical wonder but could have been engineered with a much more simplistic design. The first thing I knew needed to go was the Orang/White and Light Blue/White wires. They belonged to the running lights on the original turn signals. It’s these wires I suspected might be causing my no-blinky malfunction. Let’s clip them and toss them for good.

After I took the whole switch apart I cleaned the grease off of everything, including the weird sliding switch mechanism.

Filthy.

These little sliding things come off too.

The spring switch part was also covered in grease and grime. One more interesting aspect of this piece is that there is a ball bearing that’s used to either: 1.) Ground the switch, or 2.) Help slide the switch from left to right. Be very careful and don’t drop it and lose it.

The bottom housing, once again stuffed with some kind of lubricant or grease.

I cleaned every bit of it.

Here you can see the ball bearing back in the housing. It sits in a little triangle groove which has a slit that runs left and right. The other set of wires that I found odd in the switch were the Brown/White wires. The CB550 manual defines these as the tach and speedo bulb wires. Meaning that the lights in the speedo and tach are for some reason running into the turn signal switch which means they are also unnecessary in here. The Brown/White wires are set up to be actively fed power either in the middle, left or right switch mode. Totally unnecessary, we can feed those bulbs power from within the headlight bucket. Let’s de-solder them and get them out of here.

There, as it should be. All we need are the left and right turn signal wires and the pulsing gray wire coming from the relay.

I also went ahead and trimmed some more length off the wires in the headlight bucket.

As a rule of thumb if I take off a fastener that’s rusted or stripped I never put it back on so these bolts are going in the trash.

My local hardware store didn’t have the stainless steel fasteners in the 25mm length I need to replace the originals so I had to get black. These black allen head bolts will eventually rust. I coated them with a little WD40 before installing them.

So, all done and still I’m not getting any blinky-blinky. The lights just come on and stay on as they did before. I have successfully narrowed down the problem. It’s not the switch. Now I’ll have to look carefully at the ground wires in my bucket.

Good day gentlemen. See you next weekend.

I’m nearly done with my LED conversion. My new front turn signals came in yesterday evening. They’re all metal, chrome, LED goodness. I couldn’t have chose a better style to suit my front end.

I bought them on from Demon Cycles. Even though they are made in Taiwan, I can vouch that they are well made and brighter than any incandescent bulb. The chromed metal is flawless, and the lens cover and LEDs are well constructed. They are small, have a tiny footprint, and don’t stick out like traditional signals.

18 super bright LEDs. Two wires. Yellow = power, Black = ground. Plug and play. Easy. I popped them right into the orange and light blue harness. No need for the orange/white and light blue/white wires since I won’t be using these as running lights.

Step one: Remove the headlight bucket bolts. These are the same bolts that the wiring harness uses for grounding. The threaded bolts of my new signals will replace these.

The front signals now provide three functions: Signaling, holding the headlight bucket in place to the fork ears, and grounding the wiring harness. Nice.

Clean.

Tonight I’ll post some video of the new signals. They are extremely bright.

Next up on my moto agenda is to replace the gauge lights (speedo / tacho) with new LED bulbs. The bulbs in the gauges are burnt out most likely. I’ve never seen them illuminated. I’d like to replace the pilot light bulbs with LED as well. The only bulbs that work are the neutral and hi-beam indicators.

After several weeks of trying to get my LED turn signals to work, I finally succeeded this past weekend. The problem I was having was the signals weren’t blinking. The controls would activate them correctly, but they just stayed lit, no blinky blinky.

I tried using an LED relay from Harrison Specialties. It didn’t work.

I tried replacing the stock thermal flasher with an electronic one. Still no blinky.

I returned the electronic flasher for another. Nope.

I finally decided to buy a ELFR-1 from customled.com and still nothing.

It dawned on me that my problem had nothing to do with the flasher or relay, it most likely was my wiring in the headlight bucket.

So, I decided to take it apart and put it back together again.

I cut every wire. I cut for two reasons:

1. I wanted to shorten the wires to make a little more room in the bucket. The excess length was from installing the clubman bars.

2. I wanted to replace the bullet ends.

My process began with stripping the thick black plastic harness, then cutting around 6 to 7 inches off each wire. Oh, I decided to remove the turn signal buzzer also. Now I wonder if removing it contributed to my LED signals working.

All wired up with new bullet connectors. I also cleaned the ground connections.

Custom LED electronic flasher relay ELFR-1.

Two prong. Plug and play. Red on flasher goes to black on the bike. Black on flasher goes to grey on bike.

My new ELFR-1 sitting nice and cozy in the stock rubber mount. My new front signals, also LED, should arrive by the end of the week. I’ll take some video of all the signals on friday. I’ll post soon.

My lovely led turn signals are all wired up. I made everything as neat and tidy as I possibly could without the use of heat-shrink tubing. Curious that I couldn’t find any at AutoZone or Radioshack. I’ll have to look elsewhere for the tubing and then rewire the signals sometime later.

This morning I picked up two electronic flashers. One 2 prong, and one 3 prong. Neither of them worked. When activated, the turn signals just remain on, they don’t blink. This is because both flashers are load sensitive. They require the lights to pull the correct current before shutting off and then turning back on. Since LEDs draw less current they will never trigger the load sensitive flashers.

The relay I got from Harrison Specialties didn’t help either. So, since I have no intention of changing out my beautiful LED turn signals, I will have to resort to purchasing a true LED Flasher Relay that is not load sensitive and is built specifically for LED turn signals.

This is the one I’m thinking of.

$19 bucks is worth it to keep my turn signals.

I’m assuming this is a thermal based flasher and not an electronic flasher. This little guy was connected with a black wire, which I assume was power, and a grey wire that connects to the turn signal switch. I’ll head over to AutoZone this morning and pick up an electronic car flasher with three prongs.
