Check the main light switch. Park lamps does not utilise any relays and if it is stying on means the switch is not being turned off.

Yes, there is an autolamp dual coil relay for autolamp/delayed exit, behind instrument panel, right side of steering column.

If it is stuck in on position, it can result in the lights staying on.
