it costs about $90 bucks from your local autoparts store and can be changed in about 10 minutes.
my only other question would be do the lights only go out when the speedo dies..if sometimes the lights wont lite up but the speedo still works, than I would replace the light dimmer switch..when it starts going it turns off the gauge cluster lighting.
