Almost embarrassing to ask this question.... My driver side headlight bulb retaining clip is missing (Assume lost by a service technician some time ago). Subaru (bless'em) will sell me a complete headlight assembly, but can't supply a clip on its own. Such a pathetically small bit, that cannot be easily purchased is causing me some grief. Out of position bulb and causes very low light from headlight. Any ideas on what/how to purchase as a replacement?
