One of my high intensity headlilghts is bright white and the other has developed a purplish tinge. Does that mean the bulb is going south on it? They’re only over $100 for the bulb and 25,000 volts so not something to fool with lightly. ---

It may be the lamp or the power supply. Both are expensive. I wonder how often a high resistance ground might fit into this? In any case this is reason #3 why I believe HID’s are a very bad idea. We had a great system with the old sealed beams before the designer types convinced the law makers that looks are more important than lighting. ---

Swap the lamps and see if the problem follows the lamp. A bit of work but better than guessing. Does the lamp envelope appear to have a coating on the inside or is it nice and clear like the other one that is normal brightness? A bad ballast or ground can damage a good lamp if allowed to run too long under those conditions. Best to address it sooner rather than later… ---

Huh? Update how many years later? 7 years? Why my stuff keeps coming to the top I dunno. At any rate, yes, changing colors from white indicates a dying HID bulb. Acura wouldn’t replace it though until it went completely out, which it did and which they replaced at no charge. It was the $250 or so bulb. 50K bumper to bumper where they take care of everything. Geeze, I’m on my third Acura already and this was the first. ---

Bing - just curious , what setting do you have that puts old threads up or are you talking about the ones you made when reading threads. I have the box set on all categories and latest because if it past a day or two I know longer care. ---

I haven’t put any time limits on it that I know of. It just show up near the top on suggested topics and lo and behold it’s one of my old ones from years ago. ---

When I am logged on and reading threads if I scroll down to suggested topics they are all ones that I have made with unread replies. Like I really care a year or two later. ---

Maybe I’m the only one seeing them then. I dunno. ---

I see a lot of ancient threads started by me in my suggested topics as well. They were all started long before this version of the forum, so I suspect this forum thinks that I started it, and then never looked at it again - so it’s recommending that I check for replies to the topic I never revisited. BTW, if you didn’t know, turn that auto headlight feature _off._ It tends to turn them on in the garage or going through tunnels, and then they get turned off again a few seconds later. Rapid on/off cycles are what kills HIDs much faster than they should die. I retain manual control of my lights, and I’m still on the original bulbs in my 07 TL. ---

The ‘suggested topics’ section seems to be the cause of many of these old threads’ rebirth. And I find that section of no use at all. ---

I agree. The _suggested topics_ section is always visible on the lower part of my screen when I’m looking at posts. Luckily I recognized that those were old posts of mine and ignored the section from then on. But I can see someone clicking on one of them… and opening an old topic. ---

@cdaquila Carolyn, I know that when reading threads (while logged on the ones at the bottom suggested block are mine-still would like to be able to close them ). What does someone see that has not started a thread ? ---

Volvo, I am seeing ones that I stopped reading from a couple months ago: best homemade parts washer, snow tire discussion, tiller, etc.
