I think you can get to the side light bulbs by removing the grills under the front of the bonnet just put your fingers through the grill in question push up and pull out at the bottom at the same time, there are little platic tags on the bottom that go in to slots, remove the grill and you can see the side light bulb holders, it is a bit tricky but it can be done, Best of luck.
