Hello, my name is***** you tell me if the light seems to be brighter than the other headlamp when they are on?

Customer: replied 1 year ago.
Both low beam bulbs are very bright when on. Both left and right reflectors are melting above the bulbs. The right reflector even has a glob of melted plastic extending from top to bottom of reflector.
Customer: replied 1 year ago.
Both bulbs as one spec.
Customer: replied 1 year ago.
Both bulbs are oem spec.

Thank you. I have one last question. Do the lights get brighter when the high beams are turned on or do they remain the same?

Customer: replied 1 year ago.
I don't know and can not readily find out. The car belongs to my son who does not live with me. It would have been nice had you asked this question at the same time as the last question when I still had access to the car.
So let's assume the lights get brighter. What's your solution?
Now let's assume that they do not. What's your solution?

The only thing that would cause this would be if the high beams are staying on instead of the low beams. The low beams would not get hot enough to do this unless the headlamps are cheap aftermarket ones and not original. If they are original then the high beams are more than likely stuck either due to a bad relay or a bad switch.

Customer: replied 1 year ago.
As stated in my original post, it is the low beam reflectors that are melting. I have no issues with high beam bulbs or reflectors.
Low beam bulbs are not OEM, but are OEM spec, made by Vosla,12v 55w, PN 27078.
Well this was a waste of $5.00.

Hello and welcome to JustAnswer!

From looking at pictures of this bulb online it appears the shape and length of the bulb glass may be the issue. Can you measure from the end of the glass to the mounting flange of the bulb base and let me know what the measurement is?
