			I'm with JohnA, use a LED. 
		
		
		
		
		
		
			I used a nice blue one (blue = water :lol: ), next to my boost gauge, so I can see exactly when the boost switch is activated. There's a picture over here: http://s40concepts.net/forum/index.p...art=0&count=15 Scroll down a bit for a picture with the ignition on.

	big blue LED next to the boost gauge. You can see it with the peripheral vision, and also gives you an indication that you've passed that boost threshold

			I used a blue LED from farnells with a 1k inline resistor, I think the bulb will draw too much current and could stop the pump working altogether (it`d ground the trigger wire).
