Thumbs up Tin Foil Turn Signals

No, I'm not talking about their habit of crumpling under the slightest impact. I'm talking about brighter turn signals.

The Wee's turn signals aren't the brightest, and so I've been keeping an eye on upgrade options, including this thread which just confirmed a great plug'n play 4W LED solution.

https://www.stromtrooper.com/techy-wo...install-3.html

That got me thinking about how to figure out relative brightness and field of view for the LED's vs the stock bulbs, given the output characteristics of both, without actually trying it. I quickly realized that I had to find out what kind of reflectors were in the turn signals before I could puzzle that one out.

So I took apart a turn signal for the first time ever and found...

No reflector whatsoever! Just a black plastic hole that half the bulb's output gets sucked into.

Gee. Any sort of reflector should therefore be a major improvement. Enter pair of scissors, scrap of foil liner from a cigarette pack, and viola, instant reflector.

Result: At least 50% brighter turn signals!

Cost: Nothing but a bit of time.

After the test on the first turn signal I went ahead and did all four.

I might even have to upgrade the foil to those little aluminum tart trays... :mrgreen:

Interesting. I just ordered a new left front turn signal, so I'll look into the lack of reflective material. My only suggestion to your post would be to quit smoking and use Reynold's Wrap

Yep, it's a really good bang-for-the-buck mod. There's an old thread about tinfoil inserts around here somewhere, I modified mine the same way last year (just used regular Reynold's Wrap instead of cigarette foil though).

You can buy a roll of silver reflective tape and cut sections to fit into the casing...self sticks. I did all 4 in about a half hour.

pick up metal tape in the same area of the big box stores you would find duct work.. this is what you actually use on ducts rather than duct tape

I did my Vee's rear signals a couple of years ago, and I could only tell just a tiny difference in brightness. I compared with foil and without and you can tell a small improvement, so the foil stays in.

Don't use foil unless you can glue it down or use double stick tape. It will come loose and short the light. What you can use is the stuff the HVAC people use to seal ducting. It's basically aluminum foil with tape backer.

Yea its the best cheap mod that you can do to the bike. I got a little improvement in my lights, but everything helps. I used the aluminum foil tape that I got a Home Depot.

2009 DL650 Oort Gray Metallic Edition
1985 Honda Rebel CMX250C
(Bike rescue/rebuild project)
2003 SV650 Fast Silver Edition

If it aint broke, take it apart and make it better.
