thinking of using this,someone on Series and fenders on fb,gave a simple way to wire it using a relay Premium Quality Automotive Relay 12V 30/40Amp 5Pin C/O With Bracket - By TYCO/TE | eBay
Earth to one side of float, other side of float to 86
Fused batt (adequate for bulb) from ignition on feed to 85 & 30
87a to bulb
Earth to other side of bulb.

using this exact set up i now have a working low water sensor

i fused the ignition supply at 5 amps,i still need to tidy the wiring and the led i bought for the lamp was faulty FFS,

,anyway i borrowed the spare 24v bulb instead as a temp measure

Was the led rated at 12v & did you have it round the right way?

It's not a bulb. It's a diode and won't show continuity in one direction.
