I replaced all the original lights
on my Trillium
1300 with a complete lamp from Princess Auto. I used 2 double light
units one over the sink area and one over the table area. I made a bracket to mount the table light on the closet near the ceiling. I used 2 single units ,one on each end of the upper cabinets. These were a simple 2 wire hook up once you cut off the ends of the original lamp fixture wires. (they are polarity dependant so switch the wires if they need to be) You can just buy the bulbs but the old lights
will not be anywhere as bright as a replacement LED lamp fixture plus the new LED's use 80% less current.
The catalog numbers are: 8381063 & 8488702 I believe ,verify this with P.A. they do have a on/off switch on them as well. I hope this information may help you with your upgrade. Happy Camping ! Duane
