Hi mate. You US military?
The red Triangle is a general fault indicator, usually it and another, more specific, warning light come on together.
The warning lights on the right hand side sometimes fail to work because the solder joints have fractured. It's often repairable, you should be able to find more info if you search our archives using the Search button .
Also, if the Cig lighter isn't getting power it can cause some seemingly unrelated electric issues (TBH I forget exactly what kinda issues at the moment). Check the Cig Lighter fuse which IIRC is in the driver's footwell on the RHS. It's difficult to see the fusebox if you don't know it's there.
