Martin, be sure to ck. if they run DIRECT off of 12VDC as some LED fixtures I've looked at have to have an expensive power supply(not a space problem in a truck).
Also, if you use the dual face version on the bike front you may have to put some foil or other barrier on the back side to keep from blinding you during night turns.
Please post your findings and esp. if you buy them as I am interested. Be careful. Bob.
