Just keys, Viper system.
They house key has a built in Red LED.
On my jacket zipper I have a mini photon light. Why?
CUZ THE FUCKERS DIDNT USE A YKK ZIPPER AND IT BROKE OFF, THATS FUCKING WHY!
Dont ever get anything without a YKK zipper. There is no substitute. Ever.
3 keys & a Photon light is all I really need. I used to carry the "Esquire Micro-Light" Swiss Army knife too. Never really needed the flashlight built into it since the Photon is better, but the scissors got used a lot. For some reason TSA frowns on carrying knives on planes though, so left it at home last time I flew and haven't bothered to put it back on the keys since.
Shortylickens, I'm sorry to hear about your zipper but glad you were able to find a much higher quality replacement zipper pull.
