I wanted to know what are the brightest
best legal low and high beam bulbs (brand, number etc.) for my C6 2010 Grand Sport Convertible ? I have a hard time seeing at night. Thank you.

I'm not sure you will benefit from some of the bulbs on the market, like from Sylvania from Autozone or similar. Potentially...

Most high-output headlights are aftermarket projector - can research those here on the forum...however somewhat expensive.

The best HID lo beam bulbs are D1S Sylvania/Osram 66140XN and the best hi beam incandescent bulbs are H9 Sylvania Silver Stars. These will be a nice improvement over your old OEM bulbs, assuming your external lenses, internal projector lenses and reflectors are in good shape.

That said, the best available C6 headlights are Sharp Light Innovations' LED projector system for both hi and lo beams




Just lots of useable white light and 100% street legal
