As you can see on picture #2 I have changed the DRL from regular bulb to LED (P13W type) - the difference is amazing. I have also changed the W5W park bulbs to LEDs - waaay brighter, did the same for the licence plate light. Replaced the OEM H4 road lights, changed them to Osram Nightbreaker bulbs - give much more light.
Once the Osram goes off I will buy some Philips LED retrofits (not fully legal in my country but oh well...)
