Speedo backlight bulb burnt out

Noticed on the way in this morning that the tach has a nice backlit gauge but the speedo is dark. Anybody replace the bulb before? How much of a PITA is it? Is the bulb an off the shelf one or a Honda special?

Can't tell which one might be your bad bulb, but here's the parts diagram.

Thanks to you both... For some reason I did not even think of looking it up online... Need more caffeine.

Holy Shi! You can look up assembly drawings on the Ron Ayers website? That's awesome. I didn't see 05 or 06 models to choose from though. 04 is late as they go.

The changes from 04-06 were small enough that 99.9% of the parts diagrams will be relevant regardless of which year you have. Obviously color is an exception to this statement.

I thought my tach light went out, I put it off fixing for a week and it started working again.

It shows 4 bulbs total - 2 upper and 2 lower; it's probably the upper bulb on the tach side. It looks like they pull out from the back - the gauge cover (part #16) removes with 5 screws and the wires exit the bottom of the cover - everything is really easy to access.

put some of those hyper blue ones behind it,, it makes the face a little more interesting, as the stock ones are great,, but definetly not a modern look..

So you're saying these are regular bulbs, not some Honda specials?

I looked at it again today (yeah, I still haven't fixed this) and realized I have to un-mount my windscreen to get the gage covers off. Sux... That windscreen was a bit of a pain. If I take it off, I'm not sure it is going back on.

Here's an option if your interested instead of regular bulbs.Might be useful if wind screens are a problem to remove.I bought a set to replace my tail bulbs after blowing one only after 4000 miles.
I have used plug & play LED's in my offroad bikes tail light for two years w/o fail,I used to strech out the filament in stock bulbs.It looked like a rollercoaster ride inside the bulb.

For best results the LED color should be the same as the lens color. As an example: a red lens will filter out all but the red portion of the light so if the light is all red, none or very little light will be blocked by the lens. The light from a White LED contains very little light in the red portion of the visible spectrum so most of the light would be filtered out by a red lens.

Also note,Before installing in the instrument cluster:
They have many types in ea. style of bulb,they might or might not work?
I haven't tried a luminary application yet.

LED bulbs are generally not as bright as standard incandescent bulbs, they have many advantages over filament bulbs (longer life, faster on/off times, lower power consumption, more vivid colors) but brightness is not one of them.
They are generally not as bright but some of them with large numbers of LEDs, will appear brighter than filament bulbs.
As an exception, the new 3 Watt Luxeon LED car bulbs are as bright or brighter than most standard filament car bulbs.
The light is distributed differently so they can appear brighter in some applications and not as bright in others, it depends on the size and shape of the bulb housing and reflector.
Most LED bulbs emit light like a flashlight, all out the end. Regular filament bulbs emit light from the end and all sides, so they will be better suited for some lighting applications than LED bulbs.
This is the same reason why they do not rate LED car bulbs in lumens or watts, they would be a deceptively low numbers because the light is measured from all sides and the end on standard filament bulbs, but only from the end on LED bulbs.
