I would be happy to help!
To add clearance lights to your 2017 Entegra Coach Aspire Motorhome I recommend the Red # 328-K-52 and Amber # 328-K-51. These are two diode LED lights like you were wanting, and install by surface mounting to your motor. Based on the pictures I was able to find of your motorhome it looks like it has some oval lights, so these will blend in and not look out of place.
You will need to use # 16-1-1 and heat shrink butt connectors # DW05744-10 to connect the lights... view full answer...
With the LED Strip Ligth Kit part # DG52694RF you can add onto lighting with the strip kit part # DG52697. Each section of this equals an additional 33 feet of light. view full answer...
