any LED replacements for the ones that light up the speedo, tach, temp and fuel ones. i looked at the back of my cluster and those seemed to be a totally different bulb, they look like a metal housing for those bulbs.
Great DIY instructions from the OP! Did this today and everything went well without trouble. NOTE-I highly recommend that you get an interior trim / molding tool kit from your local auto parts store if you don't have one. This makes removing trim easy and not damaging the trim pieces a must.
The other bulbs were stated earlier in this post as being #74 from the auto parts store but those were a little fat and didn't look like they'd fit into the bulb holder. O'Reilly's had slightly thinner bulbs #2721 ($5 for a 2 pack) which also said "Replaces 17037". The part number at the dealer without the holder: 9098111018 ($5.19 each). The bulbs so come out of these tiny holders by trying to pry them while pulling at the same time.
FYI: These bulbs, which mine has about 24 on the back of the cluster (I'm eating and don't want to count again), also fit the bulb for the shifter position indicator light in the center console.
FYI#2: The bulbs for the joint lighter and ignition are the same: 8499910250. These are bulbs attached to a harness.
I got a set of 5 incandescent bulbs with the base that works with the RX dash. The cost is $1.00 and shipping/handling is $7 from All Electronics. I order a lot of electronic parts from this source, they are reliable. With the time savings and the price of gas not a bad deal....
