So for my 1999, I'll need the 4 194 bulbs (green) for the gauges, 5 yellow 74's (CEL, SLIP, TRAC OFF, REVERSE, ABS) 5 red 74's (BRAKE, OIL, BATTERY, SEAT BELT, DOOR AJAR), 8 green 74's (Igntion cylinder, PARK, NEUTRAL, DRIVE, 1, 2, and both turn signals) and one blue 74 for the high beam. I only intend on replacing the instrument cluster, I'm not touching the AC controls. I'd like to have green gauges like LouisvilleGuy32 has. Sorry that I really don't know about these things, but it looks really straightforward to replace, no soldering? Another thing I'm wondering about is the twist lock holders. Which areas need them other than the 4 gauges?

I only replaced the 194 bulbs in the cluster and 74 in the AC/Hvac, key as well also NEO 4 in the Hvac, I highly recommend replacing everything as a set to match otherwise it won't look the same and might look goofy. I should have replaced the P,R,N,D,1,2 as well but didn't feel like paying more, the green is different . The 74 bulbs I got came with twist locks attached so install was a breeze.

Much thanks, I'll go for the ones with the twist lock. My D bulb is burned out. I plan on having them all match the original, save for the gauges. These will be much brighter right? Which 194's do you recommend?

i need to replace some of the bulbs as well; thankful that someone's already done it successfully=).
for whatever reason, the haynes manual i purchased says/recommends that the srs system be disabled when working around the steering wheel area. after reading this thread i think it's excessive though i understand their mentioning it as a safety precaution. but out of curiosity, how would one disable it? do you disconnect the battery?

Disconnecting the SRS system is done by disconnecting the battery. It is also completely unnecessary when replacing bulbs in the dash. Remember though, almost every SRS connector is YELLOW, and also most of them have double retention mechanisms(a latch, and then a latch cover or something). If you are going to unplug ANY of them, the battery must be disconnect, and not reconnected until all connectors are plugged back in.

i followed the instructions in this thread and changed the bulbs in the instrument cluster on sunday. for those of you who need/want to change the bulbs, i would recommend following the procedure listed here. my two cents of advice would be: when removing the dash that has wiring plugged in behind it (mirror control and hazard switch), don't be afraid to gently pull it forward until you feel resistance. in order to unplug them, you'll need to maneuver your thumb and index finger into whatever space is available. though not impossible to perform with large/big hands, it will pose a challenge. the pics i took are of the hazard switch and mirror control. the red circle shows the positioning of the tab you'll have to press down on in order unplug the connection (hazard: black tab positioned to the right; mirror control: white tab positioned on the bottom).

the car in the pics is a 98 avalon.
(the file name says 'dimmer switch' but it's really the mirror control mechanism=)
