As you consider lighting option, you might want to look at LED's. These lights continue to improve and are a huge improvement over incandescent-types. Several advantages include long life, lower electrical requirements, severe service use and a white light available in either flood or spot beam. Quite a few folks here use the LED's (myself included) and I don't think I've read anything negative about them. These lights are now available at the big box stores, Wally World, amazon and any number of internet sources. I still have the OEM lights on top of my 1100 cab which I will eventually convert to high lumen LED's.
I just had a idea... these do come on rare occasions..... Is it possible to make your average run of the mill LED light into a strobe light? Mark may have some ideas here. What circuitry would be required if this is possible?
