The H340 came with a built in courtesy light at the front of the console. The bulb is a 10w incandescent 44mm festoon bulb and the fixture is sealed with an o-ring so its at least water resistant. Wanted more light and to go with blue LEDs like the newer boats.

Pictures are:
1. Original incandescent
2. Replaced original with blue LED automotive bulb for about $8. Added 3 new LED step lights (about $10 ea at WM) and wired to the existing switch so all 4 lights come on at the same time.
3-5. Installed two LED tri-lights in the arch. These are i2systems profile series and can be switched from off-red-white-blue with a regular SPST switch, also installed in the arch. These were fairly pricey ($85 ea at Defender), but are really cool.
