Here's a great little light that has a small hook that folds out and you can hang it in front of the vent intake and it will shine directly on the hole for the dipstick when you check your oil. It cost almost $2! It's not the brightest/best light, but I've found it's a pain to get that spot lit to see where I'm trying to jam this thing in. I'm always a little nervous about just jamming into a dark spot.
