Some time ago, I shattered the housing of the right rear turn signal. It's been held together with electrical tape and JB Weld for at least a year.
Lately, I've wanted to line the insides of the signal housings with something (BBQ tray material, or trailer tape) to make them brighter. That's hard to do on a housing that's falling apart as you try to work on it, so I went shopping for a replacement signal.
I wasn't going to buy a Suzuki original assembly @ $65, so I took a chance & ordered one of these off eBay for $19.99:
There is a cheaper version ($16.95) that is just the shell that sits on the end of the stalk, which is the only part I really need:
However, it states it ships from "China/Taiwan/Hong Kong" & I'd rather not wait a month-plus for shipping.
It's interesting that this item claims to be for any signal position (front/rear/left/right). OEM replacements are listed for each position, with 4 corresponding part numbers. Maybe the stalks are different?
Alternately, I could have swapped out the rear turn signals for totally different ones. However, I wanted to keep the stock bulb sockets & wires. They just plug right in to the bike's wiring harness. That's valuable to me. Fussing with electrical terminals is a pain in the butt, & I prefer to minimize it when possible.
I'll post an update once I get the replacement signal assembly. I wouldn't be shocked if it were not in fact a drop-in replacement, and/or required hand fitting to work.
FWIW the factory turn signals are modular, and quick to assemble/disassemble, once you know a couple of tricks. I think they are a good piece of engineering - resilient, and easy to swap out just the broken parts, if something does get broken. Only real downside is that the Suzuki replacement bits are hugely overpriced.
