Looks great, love the red horn switch. Never understood why some OEM's use black for the horn.Glad to hear you got the arch lights working (and everything else). I installed the Lumitec Mirage RGB on my previous boat and really liked them. I'll probably upgrade my current boat but if I do I will probably just do the blue/white version. I liked the RGB but it was a novelty and just made it more complicated to get the color/intensity I wanted.
I also had issues with helm switches on my previous boat. It was a 2006 and I bought it in 2019. I chased some strange electrical problems with the nav/anchor light and the also the stern light. I finally pulled the switches, jumped the wires and verified the switch was acting strange. I think most of these boats use the Carling Contura style switch. I bought new Carling switch bodies from New Wire Marine and they worked perfect... problems solved. I ended up replacing all the helm switches to ensure I didn't have any other problems in the future.
New Wire Marine has a great tool for $4 to pop the switch cover off. Without that tool (or incredible skill/luck) you will break the mounting prongs on the cover. Here's a link to the tool: https://newwiremarine.com/product/removal-tool/
I also ended up buying all new switch covers - Etched/Backlit Contura V Style. It was a nice upgrade:View attachment 153382
