Review on 🔆 LASFIT 9004/HB1 LED Bulbs - High-Performance 60W 6000LM Conversion Kits with Internal Driver for dual beam - 6000K Pure White (Pack of 2) by David Tison

Fitting this 9004 to my 1992 Mercedes 500SL was relatively easy. When the road is dry, the low beam is much brighter and whiter. However, the high beams aren't as bright and don't shine as far as the OEM 9004, which is a bit puzzling and disappointing. Since I mostly use low beam, that's an improvement. I'll see how it works when the road is wet or in the rain. The headlights generate a lot of heat, to the point where the plastic rear cover of the headlight became very hot after a few minutes of operation. After drilling three 5/8" holes in the plastic covers for airflow, the temperature becomes more bearable.
