@smarty,
In my opinion, both bulbs [Left and right] should have been replaced at one go. Replacing one bulb with new and other with old, I suspect to be the problem.
Check once the Alternator is charging the battery. This can be checked at any battery shop.
Also get once the ECU scanned and check error codes. There should be some errors in the log file to get you the hint.
