Have a 95 Corolla 1.3. The drivers side headlamp bulb in the dipped position recently went on the blink. So I replaced the bulb. Looking carefully at the bulb the filaments still seem fine.
On replacing the bulb, the new one worked in both the dipped and the full beam positions. But it only worked for one day and now again its gone off in the dipped position.
On the full beam on the drivers side it still works O.K. (although its not quite as bright as the passengers side on full beam). But the dipped position is still not working.
What might be the best way for a novice to go about tracking down the cause of this problem please? Thanks.
