After pulling out my instrument cluster unit out trying to replace the bulb behind the Coolant Temperature Gauge. I find that out that my 98 gives me two spare bulbs to use. I simply swap it either one of the bulb behind the (ESP/BAS warning light or the FOG LIGHT indicator) since I don't have ESP/BAS on my 98. So for the 99-00 owners you could only use the FOG LIGHT indicator bulb.

P.S. This the hex screw on for the instrument cluster uses standard size <-- very american eh!


Just my 2 cents.
