Ok, not sure what TM you have but heres what I went with……. I mounted a 4″ cube light (40 watt spot pattern from Black Oak LED) on the port side of my tm bracket. Ive got a motor guide x5I and drilled the hole in the “O” in motor guide sticker. Then I used a 30 amp relay that is “switched” through the red bass on my accessory panel and power is supplied from my cig lighter( spliced in ) So in short, press red bass switch on accessory panel and it energizes relay that puts power to the spot light on front of tm bracket and lights the world up for navigation at night. No interference between light and tm. Not sure how to post pics but have no doubt that you can run at night with this setup and have good vision.
