I recently ordered 2 pairs of philips H1 bright white for my after market headlights (as in dp). Installed one pair in high beam since the HIDs in those took time to brighten up, which means cant use them as "dipper".
The next day i suddenly decided to go back OEM. So now they are H4 (also ordered one pair of philips H4 bright white) which are giving out not enough light spread as i expected. Also the reflector inside the headlight housing seems dirty and dull.
I was wondering if the H4 LED would make a significant difference, then maybe i can order one pair from aliexpress.
