Bloody awful product. 2 lights (ugly as sin) came with 3 batteries in each and 3 spare for each light (12 batteries total). NONE of the batteries worked. When I bought some new batteries at great cost - the lights didn't work - so who knows - maybe the batteries were ok...either way, beware of cheap crap.
Rubbish, rubbish, rubbish - DO NOT BUY - you've been warned.
