some folk dont have the cash to splash out on new lamps so they have to go second hand ! i have two lightforce lamps that i bought new and they are a few years old now but if i couldnt afford to buy brand new i would have no doubts in buying second hand ! as long as it was light force and didnt have a broken lense it would do the job fine , as has been said take the fuse out and the cig lighter bit off and yer all the way ! i got my last battery from the skip and it is the best batery i have ever owend it cost me nothing holds a good charge fits into my bag and i can charge it with a car batte
