The T84 I don't understand, what I can see the headlamps are the same and the connections for the blubs.

Some other GM cars with the rpo T84 are getting H4 and not the SAE pattern and glass made from real glass.

Is it just a stamp on the glass or some other combination regarding what lamp are on when?

Have noticed something odd for me that is when I shift between hi/low beam you never use them both, on highbeam I think the logic would be running them at the same time. Now you have a short delay between the beams when you shift and the highbeam get very weak with just one bulb on. How are you running them?

 

[Tonyrodz]

When high beams go on, the low beams turn off, and if the fog lights are on, they go off too.

Thanks.

I will look if the fog lights behave likewise for me next time I am out. Haven't noticed it anyway.

Was on a mission to change low/high bulbs but run in to trouble.

The glass on the headlamp say HB3 on high but on the back side of the reflector it say HB4 on both bulbs.
Now my headlght harness have HB4 connection on both high and low.

I did of course buy home HB3 for high beam, it doesn't have any hat on the bulb and are more logic in my world to be used as a high beam bulb!?

Do we have the T84 problem here or what? It doesn't make any sense that the glass say one thing, that plastic on the backside another thing.

What bulbs are you using?

Did put in amber parking light, did look quite good against the red car.



Edit. Trying give some better explaining...

Can confirm I have the T84 headlights it's say EXPORT on the back side and they did mess something up when they did fabricated this.

As mentioned glass say HB3 but the headlights just fit with the HB4 as the connection.

What I did was grinding of the 2 taps inside the connection in the bulb and modified one wing on it, did also put one oring more so it lock proper. So now I have HB3 on the high beam.

Before it was terrible high beam but now it's quite OK.
