Interior Lights
Not having interior lights was a "feature" It meant the battery could not go flat ! However times change, the roof panel was undone to fix the LED bar, and I had a ex Iveco light unit to use. Some things to consider It is wired to the vehicle side lights so that it could not be left on just by having the door open. LED lights to reduce current flow, increase life of bulb and more reliability because the bulbs are soldered in. £4.95 for a pair of BA9 bulbs (I only use one) and £4.98 for a whole set of panel lights. The LED bulbs have a polarity. Now filament bulbs can be wired either way. Usually the case is negative and the nobble is positive. But the interior light cluster is designed to be switched by the earth so the polarity is wrong. I needed to rewire it.
