[W126 Coupe] RE: Maximum bulb wattage for Bosch Euro Headlamps

I have an '85 Euro and the P.O. put 85W H4's in mine. I didn't know this 
until one of my headlights started going dim. Turns out the bulbs were 
overpowered and the heat was melting the connector. I had to replace the 
connector and now have 65/55 H4's in there, and to be honest they are only 
slightly less bright than the 85W's. I would suggest that if you are going 
to use anything more powerful than the stock bulbs that you upgrade your 
wiring as well.

Subject:	[W126 Coupe] Maximum bulb wattage for Bosch Euro Headlamps

 Just to confirm a couple of questions before ordering H4 & H3 bulbs today 
for (3) MB's with euro headlamp assemblies...

How do you order from Daniel Stern?  They have no on-line order system or 
do you Google for Narva and just buy anywhere???

Can I use the Narva 100/130 H-4's in the Bosch Euro assembly without 
overheating the assembly or the factory wiring?

I am going to use the selective yellow H-3's on the (2) sedans at 55watts 
since that seems to be the highest wattage with the yellow.  I see there is 
an option to go to 100watt but this is not selective yellow.  If I use the 
100watt H-3's in Bosch headlamp again, no harm to enclosure or wiring from 
heat??

Thanks,

Dick

and I have no interest in the Xenon set-up.
