Why are all my engine lights glowing when driving my land cruiser vx 1995? on 1995 Toyota Land Cruiser

A/T light, temp light, oil light, turbo light, timing light etc - every light that glows when you run the glow plugs is continuing to glow when engine running.

Still glows but are the lamps dimmer while driving, or at the same intensity?
