The CB350 had this weird issue when using the turn signals. When you switched on either side, the signals on that side would stay lit for a few seconds, and then verrrry slowwwly flash on and off. You wouldn’t think this would be such a big deal, but when you’re trying to change lanes or signal when approaching an intersection, a turn signal lit without flashing just looking like a broken parking light.
So I went looking for solutions and found that I could use a modern flasher relay to replace the ancient mechanical one. I decided to replace the flasher entirely because I was thinking of replacing the indicator bulbs in the gauges with LEDs, and the turn signal indicator required an LED-compatible relay anyway. I ended up with the LF1-S-PIN flasher from superbrightLEDs.com. I’ve used superbrightLEDs.com for replacing bulbs in my last two cars, and their stuff is always high-quality (even if on the expensive side).
A picture of the flasher is below. It’s got two prongs, just like the stock mechanical relay.
I already had the tank off, so I went ahead and removed the old flasher from the left side of the bike.
I removed the metal bracket that provided the mount for the old rubber relay holder, and threaded the new plastic relay onto the bolt that supported the old mount.
Clean and stable. And turn signal indicators now flash properly as well!
