Superbrightleds.com has some instrument bulbs... Straight twist lock style drop in bulbs. You'd have to check compatibility, but here is their site:

Don't forget that LEDs cause some circuits to behave differently (such as turn signals blinking too fast) Below was taken from their site:

Dash indicators reporting burnt out bulbs
LED bulbs may cause some newer vehicles to indicate a bulb is burnt out (because of their low power consumption). Some cars indicate this by increasing the flash rate of the turn signals, some turn on a bad bulb indicator. The only fix for this is to install Load Resistors across the bulbs that are being indicated as bad. Some vehicles will also disable the cruise control system if a brake light bulb is being indicated as bad, the installation of Load Resistors will also solve this problem.
