There are some LED'* in the instrument cluster. The shift indicator, for instance, is an LED. It still baffles me why they would mix LED'* and incandescents in the instrument cluster together instead of using all LED'*. The only thing i can think of is to get more money. My dealership said the instrument cluster either needed replaced, or they had to send it somewhere to replace the bulbs.

Who told you there would be more work required to replace the incandescents with LED'*? There are already LED'* and incandescent bulbs mixed in the instrument cluster, therefore there should not be any more work involved other than desoldering the incandescents and soldering in LED'* in their place which is what i intend to do when i get second instrument cluster to work on. There are plenty of places that sell LED'* for 12-volt systems.

You won't find LED'* that run on 12 volts in the same physical package (form factor). In order to retrofit an incandescent bulb with an LED you need to add a current limiting resistor. LED'* typcially run on 1.7 - 2.1 volts (or thereabouts) AND are ploarized (which makes a difference in how they are installed). The "12 Volt LED'*" on the market have this added after the fact and will not fit into the same space as those miniature bulbs. You may get lucky (space wise) depending on how the plastics of your cluster are engineered, but there are other factors as well.

You may notice that the circuit board in your cluster is white. Circuit boards are not usually white. This was done for a reason and also explains why they mixed LED and incandescent technology. LED'* are quite focused where as incandescent bulbs are not. They are using the properties of the incandescent light radiance along with the white background of the cluster circuit board to ensure even, consistent and bright enough backlighting. You will have a very tough time duplicating this with LED'* in this application because of the way these clusters were engineered. At that time, there weren't a lot of other good options.

Here'* my problem, all my lights worked until I took my car to the shop to get an indash dvd put in. I get it back and the tach is half lit, fuel, and boost gauges are all dark. They all worked and once I told them about it they said they burn out, that they couldn't have caused it. Should I press the issue about them fixing it since it worked when I dropped it off and now it doesn't or should I just replace the bulbs myself. IS the boost the same bulbs that are used for the tach and fuel off the website posted above. Thanks

well orangeninja you could press the issue if you like, but you may also consider calling GE when you turn a light on at home and the bulb is blown out. My point is that they probably jared the dash a bit doing the install and caused an already old bulb to fail just a VERY short time sooner. Yes you are right that they may have caused the bulbs to fail at this time but they would have failed anyway the next pothole you hit.. Please think about this before you press the issue any farther..
