The [[http://www.albrightinternational.com/products/ed125/|ED125]] is probably less over-kill for the application. They can be found on aliexpress, ebay, etc. for $21-$23 plus shipping from China. I've been warned not to mount them with the button pointing up as there is a risk of them shutting off if you hit a bump. | ||
