Excellent conversion. No need to cut original wiring. Headlights are nice and bright.

There is nothing like new car lights on your classic Cougar. The comparison is night and day literally. The installation was super easy. The only issue I ran into was with the high beam lights. The high beam bulb comes with three male connectors but the harness only has room for two. After calling WCCC I was advised to cut the connector in the middle, I was then able to connect the light to the harness. Although it was a quick and easy fix it should have been mentioned prior to purchase.

I just bought the halogen conversion kit after having the old head light were not as bright as the halogen . The kit very easy to install and they work great

I had my first real night drive recently in the countryside with these lights and WOW. They are brighter than I expected, and the high beams especially light up the whole world in front of you. Installation was pretty easy thanks to the well thought out relay wiring. Make sure you take the time to aim these correctly, for optimal performance and so you don't blind oncoming drivers. Since these bulbs have a European beam pattern, I used the E-Code aiming guidelines from Daniel Stern Lighting (google this and go to the Aim article he wrote for guidance).



I also opted to get the clear H4 bulbs that are offered separately, rather than the blue tinted bulbs supplied with this kit. I have no interest in the "cool white" look on a classic car, and the standard clear bulbs are a very nice bright white, not even yellowish like the old dim lights.



Very happy with the kit overall, great value and performance for the price. I'd highly recommend this if you ever plan on driving your Cougar in the dark.

I was ready to click "order," but elected to switch to the full relay kit and order it and the headlights separately to simulate such a kit. Take your time and pick a place for the relays that will be away from the door rotation - I put them near the horns, and velcroed them in with a tie-wrap safety-wire. The headlights are so dimensionally correct I didn't have to adjust the pattern. Really satisfied my desire to brighten things up.
