Stink Ten Two. The second Blazer.

[HO455]

Doing some maintenance on the Blazer today and found this mess in the air cleaner. I'm guessing there 20 horsepower there in amongst the sunflower seeds and the hazelnut.

I noticed early on that the light output on the Blazer's headlights was atrocious! This was kind of unexpected as it had a pair of Hella glass H4 light housings. Until I inspected the lights I was figuring old bulbs and/or low voltage to the bulbs. However inspection showed the silvering on the inside of the housings was failing. (See photos.) I've never seen this kind of failure on quality lights like Hellas before. Basically the fix was new housings followed by installing relays to ensure proper voltage will be delivered to the bulbs.

I installed new Koito H4 headlamps with 60/55W Vosla +150 bulbs that I sourced from Daniel Stern. And I got part of the relays installed but the high temperature ceramic sockets I ordered are back ordered for 2 more weeks. So more to follow on this one.

Now I'm eagerly waiting for night fall to go dial in the new illumination.

I had a set of Hellas do that as well, in storage with bulbs in them.

I had used them for about 5 years up north in a cold environment with lots of salt on the road, pulled them from the truck when I sold it and put them away for about 15 years in unheated but dry storage. When I pulled them out to use them they were junk, worse than your pictures.

Interesting these were installed in the Blazer which had very few miles put on it the last 10 years or so. It was in covered unheated storage. I've got a set of 7" round Hella that I bought in the late nineties that are still in use in my Burban. They had a period of about 10 years were they were not in use but installed.

It's likely Hella went to a cheaper silvering process and we are seeing the results of that now.

These to me are junk so unless someone speaks up, they're going to be recycled.
