    I plan to add some LEDs to my car. On them it says input voltage = DC12v, and output current = 6A max. I plan to run these with a piggyback (expandable circuit) from my fuse board, so will a use a standard car fuse but not sure which one to get. The LEDs originally had a cigarette lighter plug attached to them, but i plan to un-solder this and re-solder it directly to the piggyback cable. In the original plug it had a F1AL250v fuse but i couldn't find the equivalent of this as a car fuse and not even sure if it would be the same. Thank you :)

    You must be very young.:) The glass fuse was for years and years the standard automotive fuse. The 250V part of the fuse designation will work fine in a car, that is the maximum voltage it will work with. There are many different inline glass fuse holders that you can chose from to add into your circuit. Not having your location in your profile makes it hard to tell you where to look for one to buy. https://www.google.com/search?q=glass+fuse+holder&ie=utf-8&oe=utf-8

    hey thanks for the reply, i'm 13 and doing this to my dad's car so yeah not that experienced. What I meant is what amp fuse would be suitable for this, as I'm hooking this up directly into the car's fuse board. I was thinking 5amps...

    That original fuse is just 1A so I'm not sure where the quoted 6A comes from. If the original fuse was 1A I would stick with that.
    Please note that any wiring in cars should be with wire intended for automotive use (protected against heat, oil, water, etc.) to avoid fire risk.

    it says output current = 6A on the LEDs. and thank you :)

    I'm 18 bud, so I'm not too far from you. Good job, and keep learning!

    There getting as bad as light bulbs: http://www.cooperindustries.com/con...automotive_fuses/blade_fuses_atmatcmaxid.html

    The inline holders are better than the 3AG glass inline holders because something can't short. But the dash is mostly plastic anyway.

    Do not use electrical tape. Use heat shrink or self-fusing silicone electrical tape. e.g. http://multimedia.3m.com/mws/media/41168O/scotch-self-fusing-silicone-rubber-electrical-tape-70.PDF They actually have it in colors at the local hardware store. Also I would use 18 AWG minimum.
