It started when one of my tale lights light bulb went out then after changing it then the fuse started blowing out.my truck is a 77 scotsdale chevy 1500.
Why is my tale light fuse keeps blowing out every time i turn the switch on?
pull the wiring harness off the back of the bulb and look inside it if you see corrosion (a green or rust color) then you know your connection is bad. if that is the case you will need to replace it by cutting the wires from the old one and installing a new one. remember to always pack you wiring harness with lithium grease every time you change your bulb this will prevent your contacts from corroding. also if you replace the harness connect the new harness with a wire connector do not use wire nuts or electrical tape as this will most often result in more corrosion at the connection site.

Remove the bulb and turn your switch back on if it blows your fuse then it sounds like maybe you installed the wrong bulb,make sure it has two prongs on the bottom side of the bulb....
Remove the bulb that you replaced and see if the fuse still blows. If it doesn't, put the bulb from the other side in and see if the light functions properly and doesn't blow the fuse. If this works, replace the bulb with a new one with same exact number as the one that you removed from the other side.
If the fuse still blows, carefully check the socket and associated wiring for a short circuit.
you must have a short in the wiring. probably along the frame because that,s where the wiring runs.
