My original US headlight assembly had a completely rusted out interior section for holding the turn signal bulb. Since I wanted to keep the original assembly I was looking for a way to fabricate a bracket to hold the bulb for the turn signal. With the help from my brother, after a few visits to the auto parts store and hardware store, we decided that a piece of aluminum that is used to hold a rain down spout in place would work very nicely. We cut a hole for the bulb and drilled some holes for some screws to hold it in place and it works. It's not pretty but it works and you can't see it from the outside. Here's the pictures of the finished product.
