I've changed our 310TB over to dual 6volt batteries and am wanting to change out the interior lights to LED. I've been trying to research into them a bit and have seen where some seem to cause interference with the TV and/or the radio when on. I have looked through some of the old threads but wasn't finding much that pointed directly on the topic. This is going to be a drawn out switch over due to the cost of the bulbs but, I don't want to spend money on ones that will cause a problem. I know a lot of you have already done this mod so I thought I would use the "phone a friend" life line on this endeavor. Any advice on bulb type, brand, place to buy or anything would be of help. My end game for this whole mod is to get solar panels with an invertor set up also but that is further down the road.
