Hi there, I have tried those multi LED lens type in my 6 volt 34 ford. They only make those in 12 volt and so are not at full brilliance on 6 to 8 volts. They are also very directional. If you move off to the left or right they become quite dull. Not very good in my opinion. My car has standard bulbs which work quite well especially if you paint the inside of the light white. Regards, Kevin.
