Mine is toast. I like what it does and would like to replace it if it is being manufactured again.
Any info?

The "Smart Switch" is a plug and play kit of my headlight upgrade mod I designed & wrote up 24 years ago.  In this write-up, you can use standard 4 or 5 pin relays instead of the dual relay I mention there.  Any quality relay from say Autozone, around $12 last I bought them.  (I have a stock of them in my electrical supplies).  You need two, one ea for high beam & low.  (Recommend that instead of using one with 87 & 87a pins, as a toggle.)  If you have any failures, you can replace the relays from any auto parts store. I have 22 of these relays on Jade, similar on Deerslayer.  I've had ONE fail over the years, on my Rostra cruise control circuit.  I have installed this circuit on all my Valks.

Thanks guys. I purchased a couple of Panasonic mini 20A relays and will go that route.

I had a Smart Switch for my Interstate fry out on me after washing the bike last season.  I guess they had a common problem with that.  Mine was the "upgraded" Smart Switch with silicone, but  water still found a way to get into it.

What was the sympton's before failure? I had a couple low beam issues but seem to go away after playing with the switch otherwise been flawless for 5 yrs.

No low beam. In that Heat shrink "chunk" behind the headlight he (BonS) has a printed circuit and two tiny 10A relays. One for low beam and one for high beam. The low beam was toast. Easy to check as you can either just plug in your headlight to the original harness and see if it works or check your bulb with an ohmeter and the wiring with a voltmeter. Can supply a pic of whats in the heat shrink if you like.

Some of the early ones had corrosion problems.

I'll have to find the P/Ns but there are Bosch relays ideal for this application. Waterproof and with a built-in anti-spike diode.

I like those little 20A Panasonics that Eastern Beaver installs but the anti-spike gizmo sounds good as well.

My headlight is beginning to act up.
Light comes when I turn key to start.
Light goes out when I start the bike.
Light comes back on after start up / bike running.
When I try to use high beams light goes out completely.
For a awhile light would come back on when I would go back to low beam. Sometimes not. I would turn bike off and restart and light would come back on.
Friday morning on my way to work in the dark. Needed high beams and light went out would not come back on at all.
Tried the coast, turn off bike and restart no go.
All other lights function throughout these examples.
Start up at end of work day and light is on.
Is this similar to what you guys were having with your Smart Switch?
I don't remember how long I've had it. I think I went LED with the headlight at the same time if not, not long after.

When was the last time you cleaned/lubricated the start button on the right side.

Smartswitch is fine. Damn starter switch was the culprit. Cleaned it Sunday and light works as it should.
