In the caravan I fitted LED bulbs in the existing light units. This saves a massive amount of battery power when you are off grid – meaning you can stay away longer before you need to re-charge. Basically one 15 Watt halogen bulb can be replaced with a 3 Watt LED bulb meaning the battery will last 5 times longer on this bulb.
The campervan came with halogen bulbs and no way to illuminate the living area when quickly jumping in and out of the van when travelling. It’s got loads of light units which are all controlled by the power management system, but this needs either leaving on, or moving through the dark to the other side of the van to flick a switch.
For under £20 I fitted a roll of self adhesive LED lights which are permanently powered by a LED remote control dimmer unit linked to the leisure battery. This means that even when walking up to the van I can illuminate it like Blackpool Tower. My son can also dim the LED’s using the remote and it allows him to read in the back without bothering me (the driver). The strip also continues underneath the rear seat storage to let there be light.
The kitchen and passenger downlighters are FRILIGHT 8777 12V 10W HALOGEN - bulb G4 12V 10W
The Bus LED lamps at rear are MR11 GU4 35mm.
I also upgraded the drivers interior light with a MK4 Golf unit which includes extra reading lights – thanks to this blog post.
