7) Installation is the same steps in the reverse order

:thumbsup:

This is awesome! Thanks for creating! :)

It's not necessary to pry of the lower dash panel.  You can leave that in, reach up behind your dash and just pop the switch panel out.  It's much faster that way!

lol good to know - but either way would take me 2 secs ;)

I didn't even know that switch was lit lol.  Guess it's time to fix it. 

 :laugh: Glad to teach you somethin' new about your car, Milan!

You can also buy just the bulb at Radio Shack and change it, keeping the OEM bulb base - however, the brand new OEM bulb cost me $3.20 so I wasn't too worried about saving a dollar...literally

You may want to make a note in the first post that the bulb will be specific to coupes and sedans.  Coupes will have a red bulb and sedans will have greenish.  This is good news for me because my fog light switch is out of a sedan kit and the greenish switch has been bugging me even though I rarely see it.  

I'm ordering 4 bulbs tomorrow to fix my passenger heated seat switch, sunroof switch, foglight switch, and in the process of messing with the bulbs I managed to burn out the TCS switch bulb.

Great post, rep for you, thanks again.  I though I was going to have to buy a new switches just to fix the illumination!

I appreciate the rep! Thanks! :thumbsup: Should it have gone up though?

Hmm...maybe Tim can answer that lol...

I ordered 4 bulbs from the dealer.  I ordered the same part number because the description is the same but the part numbers change by 1 number for the sunroof, the TCS, and the seat heater.  I tried the working one in the burned out switch so I don't see why it would be different but lets hope I didn't fuck up lol. 

Sunroof          35850-SDN-A01    BULB (14V 40MA)
TCS               35851-SDN-A01    BULB (14V 40MA)
Seat heater    35852-SDN-A01    BULB (14V 40MA)

No, they're all the same bulb, I'm 99% sure, also including the Hazard switch to that list too :thumbsup:

btw, I just gave Thien a rep on the write-up for the coilovers and his stayed the same number, so I guess it doesn't always change like a counter haha Still, good shit, though!  ;D

I will defer that to Jeff.

Stickied for future reference.

You da' man, Thien. Thanks!

So is the green bulb in the fog light switch for the 03-05 sedans switchable to a different color then?    :hmm2:

Yes, I just did that on my coupe since the switch was an OEM Honda sedan switch.

Yes, this p/n is for the sunroof switch for the coupe - you'll notice the orange cover over the bulb - the sedan has a different part number but this would also work for it

Milan, is it red now?

Sure is! From green to red with just a swap of the bulb

Wow, yours is more reddish...my entire coupe's interior with those same bulbs is orange. Must be b/c of a greenish filament between the bulb and the display - a lot of manufacturers use that method - Mopar & Ford I know did for sure.

So Milan, the OEM bulb you removed, did it have a greenish colored cover over the bulb lens or was the bulb just clear glass? If you swap every over bulb to the coupe bulbs, you can have Christmas all year round! :thumbsup: haha

My interior is more this color:

The bulb that I pulled out of the fog light switch was blue (maybe with a hint of green).  I'm sure it's just my camera phone making it seem that much more red.  In reality it's closer to the pictures you posted. 

I wish all the buttons were blue..

You don't wish the buttons were blue. :jedi:

Good to know.  However, I'd want mine to be blue.  Hmm... there's got to be knockoff bulbs of that size on Ebay or something.

Blue would remind me too much of the V-dubs...

Maybe you can rig up color-changing LEDs into all your buttons then you can pick a color based on your mood, then when I drive 11 hours to come see you, I can OooOoooO and AaaHHHaaaAAhhhh haha :thumbsup:

Lol! It'd be like a disco party inside the car
