Go for it, it's high quality surface mount circuitry. $4 shipped from eBay.

 

4 bucks for a meter is too cheap

 

Who was talking about a meter? The 4 bucks is for the dimmer.

 

When I replace my halogens with LEDs, I'll probably pick up this one:
Rotary LED Dimmer with High Beam Bypass

Yeh, it's more expensive, but it has a high beam bypass, so your LEDs go to full brightness as soon as you turn on your high beams. Worth the extra money to me.

 

I used one of these after RTVing it up.

Essentially the same thing as the first picture in this thread. I took mine apart and mounted the control pot on the plastic (left side of dash). The circuit board has been velcroed underneath. It's working fine for the heated grips. High quality machine-assembled circuitry. I'm not too worried about moisture. It basically stays dry under there, and at $4, I bought a spare.

 

I use this one with my LED aux lights, and it works very well:

I think I paid 8 or 9 bucks for it delivered.

 

Here is a diagram of how to use the highbeam switch to bypass the dimmer:

 

Mcgee, got the above and looked at it today but not sure if that circuit board would be just fine without having waterproofed it? Thoughts?

Also picked up el cheapo 15 LED's while I was at it. Off tomorrow so I might farkle around some.

I've been an electronic tech for 40+ years and have a serious aversion to encapsulating circuit boards. They fail far more frequently than raw boards.

That said, it actually stays quite dry under the horizontal part of the dash. The instrument panel itself is not sealed from water. I tucked the board up where it won't get any spray. If you look around a good electronic shop (not radio shack) they used to make a spray called "humi-seal" (sp?) that provides some degree of protection from moisture. It does not have the corrosive properties of RTV and the like.

In the Boston area, we have You Do It Electronics as a retailer. It's prolly easier for people who don't have such a resource to find something online. Search on "electronic chemicals". I would, but I'm typing on the iPad and it slows me down.

 

Those 8 amp PWM LED controllers in the white housings work like a charm. I've been using two of them for heated grip controllers for several years. One I put in a neat little project box and mounted on the LH mirror boss and the other I left in the original case. However, having ordered more than just two and from different sources, I found that the actual electronics are not identical. Some are smaller than others even though they come in the same housing. Also be advised that the resistance of the potentiometer leads is critical. I initially extended the leads to allow the knob to be mounted on the handlebar with the controller located within the fairing and that didn't work. Previously, I had extended the leads on a 15 amp controller to do the same thing without trouble.
Recently I bought more heated gear and ordered these DC 9v-24V 20A PWM Pulse Width Modulation Motor Speed and this for the heated glove liners Black 12V5A Dimmer Brightness Adjusting Controller For Single Color LedLights | eBay. They probably don't work any better but appearance also counts.
