yeah those LED in the link for ebay also come in red, amber, and blue. i bought the amber ones for my side blinkers but i cant put them one because my crx is in the shop getting all the rust taken out and gettting a new paint job.

Yep... Not that difficult. The trick is really finding led replacements that are bright enough and have a decent 360° light pattern. I've got red LEDs in my stock cluster right now, but they really aren't bright enough. I guess there's not much room to work with when designing #74 bulb replacements. I'll get around to installing my '94 Integra cluster one of these days... It uses good ole 194 bulbs, so there are brighter options available. Here's the 'teg cluster with white LEDs:

Here... fresh pics. Manual white balance, aperature and exposure, so the pics should be comparable for color and brightness.
The top one is with white LEDs, but I couldn't find my third white LED, so the gas gauge end is dark. :p Each lamp is a single emitter with an inverted cone-shaped lens.
Middle is using the stock blue-rubber covered incandescent bulbs.
Bottom is with red LEDs... Same design as the white ones. I'm not sure why the color looks pale in some areas - it's just pure red in person.

I got the LEDs from superbrightleds.com if you're shopping. The #74 LEDs I'm using in the stock cluster look more or less like the ones you linked to, but with an opaque red base and flat top emitter. The pics in that auction don't look like they have an inverted lens as the description states.

so some guy put LED in his dash but his buddy did it for him so there's no write up. anybody have any i idea how he did it?

look at this post:

http://www.honda-tech.com/zerothread?id=1924927&postid=26907872#26907872

he links to a site called http://hidplanet.com

he ripped the cluster apart and soldered his own LEDs.

if you buy bulb replacements you get "hot spots" or areas that are not bright enough.

to get a better idea of what im talking about this guy made a writeup of his led bulb mod:

see the uneven areas?

All you have to do to make it controllable is put the proper size resistor on each LED so it can handle running on ~12v without cooking itself. An additional diode for reverse current protection would be nice, but not required if you're careful. Once you have that, just insert the assembly in place of the original bulbs.

Its controllable. Who says it isn't? You can wire up your own control or integrate it into the already existing one. It isn't hard.
I wasn't sure, i was asking.

Nice, thanks for the info.

I used the top ones for the Integra cluster, and second from the bottom ones for the CRX cluster.
The red #74 LEDs are just barely bright enough - if you turn up the brightness control all the way, it's probably about what you would get at 1/2 or 2/3 with stock bulbs. I used a cone-shaped dremel bit on the LEDs to get a wider beam pattern and help with the hot spots. Just push the bit streight down into the lens, forming a cone shaped divot that the light reflects off of. Be careful how deep you go though - if you look closely, there's a thin wire connected to the top of the die... Don't hit it or your LED will be useless. Needless to say, avoid hitting the other metal parts in there too. The rest of the lens is fair game if you want to experiment.
I'll try to get some pics of the stock cluster up later today.

Pics:

That's stock needle lighting... It looks pretty bright, so as you might immagine, the camera is doing a fair bit of light amplification.

I could have sworn I used a conical bit, but the bulbs in the cluster all have a spherical indentation in them. Whatever.
I just ground this one today to replace a failed bulb. I've never had a failure before now.

sweetj and i just installed these led into his dash.http://cgi.ebay.com/ebaymotors/LOT-OF-1 ... enameZWD1V

not sure if they are true leds but they are nice. we replaced the 4 across in the back, one on the bottom left right behin where its about 10mph and the two ontop that shine on the cluster.
tuned out amazing.
