Sorry for the long post. You can skip to the parts/steps and pics if you want to see the end result.
I wanted to install LED's in my 2008 330 DA cockpit using the original Atwood 2nm anchor lights (about 3" diameter). There are 2 fixtures on the arch and 3 around the cockpit with type 90 bayonet bulbs (BA15D base). The problem is the fixture is very tight and there are few LED's that will fit. One choice if you want to plug and play is the GE90 replacement from Marinebeam.com ( http://store.marinebeam.com/bayonet-90-led-replacenment.html ) which you can get in warm white (match original) or cool white (brighter/bluish in color).
But I kept eyeing the red/white switchable LED units that work off the original wiring (turn it on=red, turn it off and back on=white). There are some fixtures out there that have red/white or blue/white, or even red/blue/white but the fixtures are real expensive ($100+ each). Then I found an LED G4 bi pin replacement bulb that was red/white switchable. The next problem was by the time I added a base adapter to convert the BA15D to G4 it wouldn’t fit in the original Perko fixture. So I decided to modify the fixture, removing the BA15D socket and using gluing a G4 base on.
Here’s a parts list:
Now for pictures:
Atwood 3” anchor light (2nm) fixture with red/white LED installed
Side view of fixture housing- note black bulb base which snaps out
Old bulb/base and new G4 back pin red/white LED with G4 base
Plastic washer and G4 base glued to back of fixture
Ready for reassembly with LED installed
Turn the lights on and Red LED comes on first
Turn the lights off and back on and Warm White LED comes on

Here’s a parts list:
- Red/White- G4 back pin (5 units for $22 ea.)- http://store.marinebeam.com/red-white-led-g4.html

- Plastic washers- 1” outside diameter with 3/8” inside diameter drilled out of “Tupperware”- inner hole is big enough to pass the LED pins through
- Glue gun for arts and crafts- could use glue or caulk too
- Remove Atwood light fixture and cut wires.
- Remove bulb and base from fixture (black socket base snaps out)
- Glue washer to back of fixture
- Glue G4 socket base to back of washer with bi pin holes lined up
- Insert LED in fixture
