Tamiya light unit

[mack kid]

i will need to check out venture hoobies thanks for tip. i was wiring up lights today and first wired roof lights, hooked them to battery and worked ok. wired up to light unit did not work voltage meter on terminals gives zero voltage with switch on. did that several times going to try some other tests see if i can find out why. head lights work. but do i keep going or just rip it out start anew.
