H4 low beam headlight led (get 10000 lnms as better coverage and 6500k) 6500k is just the colour as i think is new car look but you can get upto 1200 but look cheap. 10000 luminums is the brightness output and better coverage on the road. If unsure about what bulbs you 120 needs its in the back of you manual. My latest upgrade is my number plate lights and door lights. I have bought 5x18 led pads and clear perspex 6mm. Taken my old number plate bulbs and holders out and replaced with my led ones and look cool. People probably think cheap skate but only seems to be china that sells them with 4weeks delivery. My door light upgrade is i bought 2x amber wedge bulbs 15w for my front side light just as an experiment but since you have to take the front bumper off to remove the headlight components just not got round to it. I removed the door light components and removed the glass to remove the wedge bulb. You will need pliers or something to remove the bulbs as very tight fit. I replaced with 15w amber wedge bulb and wow what a difference it makes as so bright and looks cool (just my opinion anyway ). You can get clear ones with same wattage on eBay . Everything i have mentioned is off eBay expect my headlight and fog light leds. I will take pictures and upload to give other members just basic ideas on how to get with times for very little money without leaving your house .
