Twin Crusader 6.0L engines.
When I turn the key on one engine all of the warning lights are supposed to come on briefly so you know that they are working. However the water temp light does not come on. The other three lights do come on and then go off once the engine is started. Once the engine is running the water temp goes up to normal and stays there while the engine is running. Hence I believe that it is a light problem.

On the backside of the dash the lights are on a strip with a single wire connection at each light and a red line connection at one of the lights. I believe that this is a ground for all of the lights. I believe that to replace a light the entire strip must be replaced with the light connections soldered in place.

Appreciate anyones thought on whether my diagnoses is correct, where to get a new light strip and any installation suggestions.

Many thanks
