The glove box fuse keeps blowing because the LED creates a short between the metal prongs (of the light housing) which contacts the metal of housing bracket itself. The simple solution is this.... put electrical tape on the metal bracket housing so there is no contact with the metal prongs from the plastic light housing.
Here are some pics of what I mean.
These are the metal prongs that make contact with the metal housing bracket
Here is the metal bracket, I place electrical tape at the contact points where the prongs would make contact.
next insert your led
presto, now your glove box is led status
No need to mess around with fuses of different amperages.
