Every attending I've seen uses the otoscope or ophthalmoscope light, which usually fits in with the exam they are doing. Seems pointless to buy one, plus you can by a 6 pack of penlights for 5 bucks, or use your cell phone's light.

A good steth is probably best gift.

However, shears are easily second best, they are unbelievably helpful and no one ever has a pair, especially the kind that you can use as a wrench for caps that are on too tight.

Just my two cents
