Here are two handy ones I use besides the types already discussed The blue one is from Harbor freight,$2.99 on "sale" with a hook that folds into the back and swivels as well as a magnet on the back.It has a field of LEDS,and a flash beam on the end The red one I paid about $17 on Amazon.It has a swivel base with magnets....I just used it this w/e,stuck to a frame to give light to backing plates when bleeding brakes. Both use AA batteries Cheap little lights, but handy for tight areas
​I bought this at the local parts house about a month ago. You take the incandescent bulb and forehead burning steel shield and pitch them. Screw this in it's place and you have LED light with no heat and the hook and it's even flat to stay put. Well most of the time! It's made by PROLITE ELECTRONIX Model # RTL30 if your interested.
Those halogens on a stand are great in the summertime, outside..........will attract every flying insect from all surrounding counties. But they are bright. Do be careful with those curley-cue bulbs......if broken, and you get cut or scratched by them....you can have a terrible problem, from what they say. They even have rules for disposing of those bulbs, and disposal bags to put them in. Some places have receiving bins for them.....think I saw one at Home Depot just the other day. I think there is info on the 'net if one is interested in reading further about those bulbs. The only drawback to the "wand" style I found is it seems a bit too big and unhandy for working under the dash.
The round red thing is great. Just got one (from Amazon as well) last month and it's my new go-to light for working under the car.
nothing more dangerous than an incandecent light bulb in an environment of combustiables..especially one without a cage. I lost my garage three motorcycles and a 68 dodge charger and almost my life to an incandecent trouble light
