Almost the same as me mate first time I changed all my bulbs... jacked up, removed wheel, removed arch cover, changed bulbs, replaced arch cover, put wheel back on, jacked down....
Only to find the Grey cap that covers the main lights on my tool kit.... jack out wheel off... Worse still I did the same on the other side!!
Need to change indicator bulb again now, phillips one has only lasted 4 months... not happy, I cant indicate that much... can I...
