When moving from full beam to dip, the headlight stalk does not always spring back correctly. The full beam blue light is not illuminated and I only become aware when oncoming motorists flash me. A firm 'on/off ' is needed to properly switch off. Very occasionally, on starting in the dark ,it is neither a full nor dipped beam - somewhere in between. It must be a poor connection or weak spring. (?)
It's practically impossible to demonstrate at the Dealer because occurs when driving and using a quick, light touch to move the stalk. And frustratingly, the problem is intermittent ! (Car is 2015 IS300 with 48,000 miles). I wondered if anyone has experienced this and their solution.
