Problem with front lights

[Flying Dutch]

My moterhome has a problem with the front (white road) lights. First of all the moterhome is 25 years old. Now when I turn on the lights for 20 seconds everything is okay. Then the lights start flickering. Every time faster until they completely stop. Underneath the fuse box I can hear a clicking sound at the same time of the flickering of the lights. Any idea what can cause this? Thanks in advance

Sounds like a weak breaker or a weak light relay. Feel with your fingers where the sound is coming from. Jim

I would bet that the grounds for the lights or relay are coroded or bad.

25 years on the road can have even loosened screws.
