I have removed the amber roof light, and made repairs to the mounting holes, ordered a 5 lamp spot light bar to fit instead, this is not the LED strip light but 5 spots on a steel tube 125mm long, this will be on a switch on the radio and the hard bed conversion looks to be on slow delivery, seller has got payment but not processed order, though Chinese new year will factor in this
