If wired correctly you shouldnt have any problem at all. What did the garage wire the new brake light into? Id check the join, as i presume they were lazy and wired it into the boot brake lights? Check to make sure that its not earthing off the body and the join is insulated. Without checking in person id imagine its a minor earth.

depending on how theyve wired it, if you pull the bulb from the back window the other lights may not work. inspect the wires if you can just to make sure none are exposed or touching. Also replacing a fuse doesnt solve the issue that caused it to blow in the first place. I think the fuse is 10amp, you could try a 15amp and see how you get on but id check the wiring first.

Never step up on fuses, if you are blowing fuses, something is wrong.
10 Amps means you can effectively have 120Watt of bulbs burning on that one fuse. Even if you got four 21 Watt bulbs burning, you only have 84W, and the fuse should hold, since this would draw a current of about 7 Amps.

Check their connections, i reckon they didn't insulate something properly. Or made faulthy connections...
