I leave my chapstick cap on 24/7 on my LD01SS in my pocket only taking it off when I need to throw light as I find the diffused light easier to use in the dark for a quick short see to put the key in the door light and it protects my car door from the light banging into it when I have keys in hand opening it *BING* the plastic cap bangs into the door from the dangling light. You can get all sorts of colors of chapstick type caps how about a purple diffuser lol
