LED Speedometer Conversion

LED Speedometer Conversion
So I finally got around to doing this based on these infamous write ups...
https://g35driver.com/forums/lightin...p-display.html
but decided to provide more updated info since LED technology has evolved since the initial start...
I only did the combination meter, clock, ignition ring, cigarette lighter and have film for the ac display just havent gotten to it yet...
I used these led for the cluster http://www.superbrightleds.com/cgi-b...ecs/74_t15.htm
13 if you have a MT or 14 for auto if you plan on swapping the turn signals and high beam... and the light that goes through the display for mileage I havent figured how to make it blue like accord freak did as it has an orange filter before it...so with a blue LED the mileage looks dark green blue...
the glove box, ign ring and cig lighter I used these..http://www.superbrightleds.com/cgi-b...pecs/74-x.html and a couple xtras I just clipped and wired into the clock light bases, but these wouldve work to, I think..http://www.superbrightleds.com/cgi-b.../specs/NEO.htm "neo4" is what they look like with a neo 3 in the vdc button IIRC..
So I thought Id post pics of how to get to the cluster cuz that was going to be the hardest part, if any...
any ways start by pulling the bottom dash cover off and remove the bolt below the hood latch, you can leave it attached and laying on the floor..
start removing the screws around the steering wheel trim
pop out the L and R combination switches which have easy press clips in it
remove this screw and the one on the other side
then this girdle
then the bolt that was there, 4 total on this piece
and then unclip the mirror switch
then you can fanagle the 2 rear clips off the back of the speedo and itll be free
Dis-assembly of the unit is easy and all the lights come out easy, I sanded the plastic with the needles on cuz I was scared to break them and couldnt get them off.
A few important notes IMO is when I was sanding different areas I moved the needle to the the side and actually moved the needle past where it had originally been ON THE ROD. If this happens you will have to move it back, but make sure ou test it with the face plate and everything apart before reassembly..if that makes sense
what happened was I put everything back together assuming all was good only to find out my speed said 15mph with out the engine running and the temp gauge was reading 3-4 clicks higher than normal..sux going back in..
also my needles dont light up anymore...which I assume is because of this:
there is a prism looking mechanism built that starts at the needle and sprawls out around the needle motor toward the light bulb holes, I assume that since a normal light bulb sends light in all directions vs a LED which had focused light, those prisms dont catch the LED light and direct it into the needle... I tried sanding some to try and refract more light but no dice...
also tried a few layers of film inbetween with a regular white bulb just to see and it looked more cany blue and wont be as beautiful as the blue led..
anyway heres the pics... eventually Ill get to the door switches and ac/heater pieces.. luckily I have and aftermarket stereo so I dont have to screw with all the other bs

brighter? yes
prettier? yes
hot spots? yes
would i do it again? no
I would rather solder in blue ccfl rings instead. I thing the glow would be better and more even, still havent fixed the odometer yet so its dim with a blue led...id leave a regular bulb in there
and also havent fixed the needles yet. havent decided if i want to try and wire leds into the prisms that reflect light into the needle or glue a SMD to the needle base like the OP who made the first write up

i found some on ebay for cheap, the craft stores didnt have crap, Im thinking tho that you may end up happier and with a more "pimp" looking dash if you do ccfl rings..
