Tib's voltage sits at 14.6 usually. 15 is a better number to work with.
LED angel eyes don't work by measuring resistance. you have to overcome fwd bias. instead, they use current. Each led set uses .040A. 4 of those together = .16A. A 5a fuse is entirely too big. Get one that is 1A or 3A.

Yep, I know. I just isntalled those Haloz and wanted to know about the fuse ;-)

LED angel eyes don't work by measuring resistance. you have to overcome fwd bias. instead, they use current. Each set of 2 leds uses .020A. 4 of those together = .08A. A 5a fuse is entirely too big. Get one that is 1A or 3A.</div>
Ok thanks, I will go for a 1A.

Sorry, I was pressed for time on the way out the door and didn't think about the terminology I was using. Forward Bias is how an LED operates. You must overcome a certain voltage level and the rest of the voltage will go through an LED. Instead of having normal resistance like analog components, a LED has nearly no resistance, but it has forward bias to overcome the P/N junction. It's alot of technical stuff that would take a long time to explain. It's the same reason that LED tail lights need a resistor bypass for an LED. The forward bias property of an LED (or any other semiconductor) chops a few volts off the top of the voltage from an LED which throws off ohm and volt readings. The forward bias voltage can be anywhere between 1.9-4.4V, above that voltage, a resistor will be the only thing keeping the voltage from shorting to ground. Before that voltage, there is no conductivity. A LED will remove the forward bias voltage from a circuit which throws off an ohm meter. There's alot of information available on the internet, check these links for more information if you'd like to learn more.
