Hi All,
Got a little present in the mail this afternoon. These will be for courtesy lighting, going to do RBG in addition but liked the ability to switch on clean white light when necessary and it was a cheap/easy switch with existing hardware. Never been so excited for it to get dark...
Thinking of adding a couple more under the gunwale just aft of the rear cupholders. Hoping it would shed some led on the engine compartment as well, but thinking I'll need to go a different direction to get what I'm looking for there. Pictures will come in two parts, I believe I've got too many.

Re: LED Upgrade - Phase 1
Here's round 2 of pics. Showed through a bit on the vents which is cool (no photo), but I can see with the RGB I'm going to have to get a bit more creative for the desired effect. Overall, pleased with the investment.

Re: LED Upgrade - Phase 1
Thanks guys, I've got a fever and the only prescription is more LED lighting.....we do a ton of night boating so it will get plennnnty of use.
As far as RGB controllers I'm still up in the air. My tentative plans are as follows:
Replace existing courtesy lights w/ LED * done
Install additional 2 courtesy lights under gunwales near rear cupholders
Install additional engine hatch lighting - thinking I'm going to swap out the LED bulb setup in there now with a LED strip, moving the existing bulb assembly to the above mentioned location, so I'll only need 1 additional bulb assembly.
LED Nav Lights
RGB cup holder rings
RGB strip lights under gunwales, helm, and in bow (location to be determined)
RGB Plug light (have any of you tried? I know I've read about it on some forum here....)
Stereo upgrade TBD, obviously w/ LED speaker lighting. Depending on how business goes the next 6-8 weeks, it may be a fall or winter project.
Outside of the stereo, the rest of these are relatively economical upgrades. My main concern is to have the ability to tie all RGB in together and have at least 2 zones so I can shut off the bow lights if necessary. Not sure which controller would be best for my application.

Re: LED Upgrade - Phase 1
The more I think of it, though, for the courtesy lighting in the rear and hatch, it might just make sense to run one led strip light under the gunwales in the rear, through the perimeter of the engine hatch (using the existing wiring for the engine compartment bulb once removed) and up the other side. As opposed to installing and wiring two new separate lights, plus one for the engine compartment.
