Hero Camper exterior lights

When we bought the Hero Camper we opted for having exterior lights installed, one in each corner of the roof-rack, with a simple controller inside the cabin. The two rear lights were facing backwards, while the two in the front were facing out to each side. This left a dark area in front of the camper. So far we have mostly used the red (the lights have red and yellow in addition to regular lights) to find the camper when parked at a dark campsite. Having a “blind-spot” in front was a bit annoying. I initially planned to get two more lights and face them forwards, but that left me with a dilemma. There are only four channels on the controller, how to wire two additional lights? It turned out I didn’t actually need more lights, I just needed to adjust the ones I have differently 🙂
