e.g. Ride 5h a week with halogen bulbs, and rides for about 4-5 months before needing to change bulb.

I've been running MR11 halogens for around 15 years. I start using them in October and use them 3 to 5 times per week for about 1.5 hrs per day. I also overvolt them by 10 to 20% (7.2V or 14.4V on 6V and 12V lights, respectively). Last winter was the first time I every had a bulb go out on me. I've changed bulbs in the past because of changes in the voltage of the system (going from 7.2V to 14.4V) but last years was the first time since I started using MR11 that I had one burn out.

These bulbs are very rugged especially considering the cost...about $3 each.
