I have some old Vista Light bicycle lights that I was thinking about trying to put in some LED bulbs in and mount them on the TDUB. They have 15W bulbs now so I was looking at putting in an LED replacement of perhaps 3 watts each. This won't bring day to night but for the very inexpensive entry (bulb price) it may be a nice add on for me. I am thinking HID as well. I even thought about amber bulbs for foggy nights since it gets winter duty and that means dark after work,

Any tips on MR11 bulbs that don't have huge heat sinks (so they will fit my waterproof housings)?
