I voted "no" but I'd opt for the choice of; "no but I'd have a light close by".
I like a few of the tactical white lights but for general use I'd use a laser aiming unit or night sights.
White lights serve a practical use but require practice and proper tactics.

ps; If you buy a white light, get a good brand with the strobe or flashing format. That could assist in control or containing a bad guy or subject in low light conditions.
