General auto electrical question
Just a general automotive electrical question. I've got a 20 ft l.e.d. light strip that I want to install under my hood with a toggle switch so if I need to then have light under hood to see what I'm doing my question is what size fuse do you think I will need. Planning on using an inline fuse for safety reasons

RE: General auto electrical question
Most electrical items have the voltage they require and the amperage they draw marked on the package along with a tag or imprint right on the product itself. Looking for that would be the best way to determine the proper fuse. But I would guess 15 amps would be plenty. If you find it on the package or light, I would appreciate knowing what it was! This could help others as well as satisfy my curiosity!

Thanks for using the forum,

RE: General auto electrical question
If you fail to find the info on the packaging or product the next best way is to base fuse size against the wire size feeding the lights. 12 gauge is 20 amps,14 gauge is 15 amps,16 gauge is 10 amps,and 18 gauge is 5 amps. If you are not sure of the wire size then bring the lights along to the parts store and ask them to compare it to something on their shelf. ALWAYS fuse smaller than the wire max rating. Also, secure the fuse "free floating" so it doesn't take the shock of road bumps. (About an inch of wire slack on each side is good)
