Re: Brake lights. L.E.D. or standered??
LED's are the way to go.
They use less current, illuminate quicker, are generally completely sealed in expoy and thus are waterproof. Some are also very tolerate to voltage fluctuation (Australian Army use them on trailers that fit both 12V and 24V trucks without modification at all.
As well, because there are multiple LED's in the unlikely event of one blowing, all the others still operate. You would need to loose about 20% of them (very unlikely) before the lights were not roadworthy.
Spend the extra to go LED - you will never regret it.
