I recently ordered the front headlight covers and know that I'm going to have to upgrade my factory 2010 v6 headlights that do not have HIDs. However, I am on a budget- under $300, less being of course better. I am unsure whether to keep my stock headlights and just put HIDs in them, or upgrade to a halo headlight with or without HIDs. What will get me the most for my budget? Also something to consider, If I get the HIDs now for my stock headlights, will they be compatible with other halo headlights if I want to upgrade them later down the road? Thanks for the help!
