The Nissan Path

Hi,

for past few months I notice right xenon headlight (low beam) flickering when I drive over rough terrain or a bump. It's like turning OFF then ON again within 1 second, then sometimes it stays ON and sometimes it stays OFF.

Lamps were both replaced with high quality Philips lamps some year ago.
The COLOR of both lamps, when on, is identical, so I assume it's not lamp faulty.

I know I must go through all relays, harnesses, balasts and it's pain because there is a battery in front of lamp and even if I take battery out, still there's very tight space to work on lamp.
So I just ask if anyone had similar issue.

Doh....it was Xenon lamp at the end. No visible signs of failure, but seems like one of them simply does not ignite. Got a pair of new ones.

Sjit... I replaced the foulty Xenon lamp and it worked. But a day after I again noticed some flickering when driving over some bumps. Ahhh...here we go again - still do not know what's wrong.
