I'm using Finish Line's Lucas toggles in my Cobra. Look "correct", work fine. Remember we're talking about Lucas Electrics (Prince of Darkness and all). The toggles are NOT industrial strength toggle switches (sealed contact, 40A contacts, etc.).
Haven't had any trouble with the switches ... but just remember what you're dealing with (Lucas)
The toggle switches you'll find at your local auto parts store for a few bucks are plastic pieces of crud. You'd be better off with the Lucas switches.
Digikey.com has some very nice toggle switches, you'll pay $10 - $35 EACH for them, but they'll last forever!
Sometimes, particularly if you are an engineer with a nice business email address, you can get some really cool and expensive toggle switches by emailing the folks who make the toggle switches ... not that I've EVER done that, nope, wouldn't be proper.
