can led dash lights blow 5 amp fuse?

outfitted all my dash lights with led lights, nothing else. I started driving car more now and today(third time out) noticed dash lights do not work. tried two other 5 amp dash fuses and they popped as soon as my parking lights came on. Been awhile since I replaced dash lights and think maybe it blew a fuse then. will led lights blow the fuse like that? Also replaced all front lights with leds last weekend and all those are working. thanks for any insight or tips to try and trouble shoot!!

LED=Light Emitter Diode. The only time I have ever seen a diode cause a fuse to blow is if it is hooked up backwards. But that usually also ruins the diode immediately. Constantly blowing a fuse means you have a high current draw somewhere. You might want to check over your work and find out if you have anything shorting.

LEDs only require around 5 volt to fire. The amount of
current to drive these is very low. That is the main advantage
of the LED setup. Like BrewGuy said you have a short somewhere.

i contacted super bright led and was told I could have a bulb out, which stinks since they aren't that old. Suggested i take all out and put in one by one until fuse blows then I'll find the culprit. Took apart most of instrument panel tonight, will look at other wires and see if something chaffed in process. thanks for the responses!

took instrument panel out out and unplugged it then turned on headlight switch to parking and fuse still popped. So could the switch cause it? It is original with 112,000 miles but the parking lights and headlights still work. Wonder if it's the wire for the dash lights is bad. Not good at electrical stuff.
