l.e.d's
 

I somehow disconnected the l.e.d to my alarm and when I replaced it with one from radio shack it wasn't bright at all. Does anyone know where I can get a good replacement that bright?

I'd google the maker of the alarm system, contact them and ask for another one.

Ebay.....

You can buy like 1000 LED's for like 15 bux there.....

The one's I bought for something's in my car I got the 5000mcd LED's which are EFFIN'G BRIGHT!.

5000 mcd really isn't that bright.

it also depends what size LED you are looking for...3mm 5mm 10mm ...

I got both 3's and 5 mm's.

Thanks guys, I wasn't sure what I could use but there seems to be plenty of options. I'll probably get some bright 3mm.

you are going to need resistors too. assuming you dont have any and the line you are using isn't already lower voltage.
