@roxy, having been on multiple forums, when someone doesn't take the advice posted or acknowledge the reply, I just leave the thread. the least we can do for each other is offer our advice on the problem/question and move on, if they like the reply and respond with their results, great, if not and they reply having ignored what was said leave the thread, that's how I deal with it.. I assume most know about the owners manual and continue on from there. in my opinion, something as simple as headlights can be left for others to answer seeing the answer was simply "they come with 9007 from factory", I would expect to see people who know the simple answer to just post that rather than redirect them to the manual. if all that is to be said is to check the manual, then just leave the thread for someone else to pick up. You know enough to be helping with bigger things than posting about the basic owners manual.
don't take out frustration on someone who may not see your past efforts on the site and witnessing the ignorance of some people who would rather not look at a manual.
after all, we are pretty much strangers on the internet talking about some car problems. it's not worth stressing over.
