Okay I found some spring loaded door switches, but there is just 1 problem now. You would have to drill into your VX to install the switch back there. I know a lot of VX guys aren't willing to drill into their rare VX just for some automatic cargo lights. So I doubt I would sell them since nobody would want to do that.

If you really wanted them automatic you could still buy these LED pods for the light source, but then you'd have to source your own door jamb switch and hook/wire it up yourself. Honestly if it were me, i'd just connect them to a little switch that's easily accessable from the cargo area that you can flip on if you need the extra light. You could even get one of those little switches that light up when off so you can always find the switch.
