Go to Walmart and there should be a area with stuff sold on TV. Get one of the torch flash lights. It a good light for the money 20$. Has a slideable head that goes from flood to spot. It also has hi/low/ sos/strobe. It the ones you see from bell and howell.
I bought one of their head lamps that has those same features. I really like it, but the battery pack being on the back of your head makes it uncomfortable if you have to lay under something looking up. Other than that, it's a great light
