Ouch! A red light on the weight shaft of a GEM?

The weight arm on my GEM is fairly high and one can easily bump into it in the dark. So far no big
collisions, but I plan to have a lot of people over for a star party. I figure putting a red LED on
the end would work; however, how does one do this within a modest cost. There seem to be two ways:
1. use a battery, resistor and LED. 2. use a resistor, LED, and an ac/dc converter. The second
choice is appealing but costs about $14.00 if one buys an ac/dc converter from Radio Shack. The
first method probably runs through batteries at a fairly good rate. I actually have a red LED
flasher ($3.00) I bought from the h/w store. It's fairly bright and flashes about every second.
Maybe it would work out by beefing up the resistor to reduce the light output. At a reasonable blink
rate and dimmer, it might work. Comments? Other choices?
