Thread: Looking for recommendations for rear mounted work light

You mob wire up the way you want to it doesn't matter to me, Just make sure you fire extinguisher is handy

wipe contacts is where on closing they are designed to move across there surfaces thus are called WIPED and are designed for low voltage 0-5 volt or low current closing .

where as the relays you are talking about are spring loaded and if dust gets on them an arc is caused by the current to make contact

no need for the fire extinguisher just rely on years of in the trade all horses for courses

c'mon people... there are far more important things to worry about than how to wire up an LED.

It's called 'robust discussion' and there are recommendations for lights and 2 suitable circuits given for people to use if they choose.

But yeah, where's the bloody pics ?? Piccy worth a thousand words (or will cause a thousand words discussing it)
