A LITTLE HISTORY
Sealed beam headlamps were introduced in the 1930s to provide a consistent quality of headlamps. Prior to that, headlamp design was left up to the vehicle manufacturer and lighting ability varies greatly.
The problem with sealed beams is that the lens, reflector and filaments are all part of a bonded assembly. When the filament burns out, the entire lamp is discarded. Consequently, the sealed beam has become a commodity. As long as it meets the DOT standard, the only thing that matters is low cost. The DOT standard allows for a very loose pattern with a wide transition from dark to light. Many sealed beams still conform to the antiquated pre 2000 DOT standard that required 20% of the light go up to illuminate overhead signs.
All of this results in lamps that dazzle oncoming traffic and at the same time supply poor illumination of the road. The sharp low beam cutoff of Hella ECE lamps makes the areas that are supposed to be dark darker and the lighted areas to be brighter. We say that our lamps are four times brighter on low beam and twice as bright on high beam. Refer to the Isolux drawings at left.

WHAT IS A CITY LIGHT?
City Lights or Position Lights are a small, typically 4 watt, bulb, mounted in the reflector of a headlight that are wired so that they are on whenever the ignition is on. They are required on all ECE vehicles world wide. Think of them as a for-runner to the Day Time Running Light, but not nearly as bright. Their primary purpose is to make a vehicle visable in many of the large cities in Europe, such as Paris, which are very well lit at night. Headlights are not allowed to be on because of light polution concerns in areas where many people are outside shopping and dinning.
The Wiring Adapter:
- The pin-out of 165mm lamps is different that other sealed beam lamps. See the chart above.
- To make this conversion simple we include our P/N HL66490, Hella P/N 003385001 which will make it plug and play.
- Some cars, mostly the ones with only two headlamps, require the H6545, 4666 or 4668 lamp. These lamps had the ground lug on an angle. I assume this was to insure you install a high/low beam lamp. At one time we could get the adapters with the angled ground, but no more. You will have to release the male connectors from their holder and insert them into the the stock connector, IN THE PROPER ORDER. The chart above will show you the proper pinout
Includes:
- 165mm Rectangular ECE H4 Conversion Hi/Lo Beam Headlamp.
- Rubber Boot
- Wiring Adapter
OPTICALLY AIMING ECE HEADLAMPS
ECE headlamps are intended to be aimed optically. This is a superior method to aim headlamps because it eliminates the effects of manufacturing tolerances and variations in filament placement in respect to the aiming lugs. Consequently, ECE headlamps do not have any aiming lugs.
Many auto repair businesses have equipment to aim headlamps optically, but not all. The advantage of this equipment is that aiming can be done indoors with the lights on and uses considerably less floor space.
To aim these headlamps yourself is relatively simple. Here are the steps.
- Adjustment of these headlamps is achieved by turning the two screws on the headlamp frame. The screw at the top or bottom will adjust the up-down aim, and the screw at the side of the lamp will adjust the left-right aim.
- This is best done at night.
- Position your car on a level surface. Pointing at a garage door or a wall, place the vehicle about 25 feet from the wall.
- Turn the headlights on high beam.
- Using a yard stick or a tape measure, as close as possible to the left side head lamp, measure the distance from the floor to the cutoff line of the lamp beam. Note this distance.
- Looking at the light pattern on the wall, adjust the left-side headlamp left or right so that the “Hot Spot: is in line with the headlamp. Try to get it correct within a couple of inches.
- Go to the wall and mark the height of the headlamp and mark it with tape, or if you own the wall, a marker.
- Adjust the headlamp so that the hot spot is centered on the mark.
- Measure the distance between the headlamps. Note this number.
- On the wall, measure to the right the distance between the headlamps and mark the wall.
- Looking at the light pattern on the wall, adjust the right-side headlamp left or right so that the center of the “Hot Spot: is at the mark. Try to get it correct within a couple of inches. This should result in the beams of both headlamps being parallel to the longitudinal axis of the vehicle and to each other.
- Using the same height measurement you used for the left-side headlamp, adjust the right-side headlamp up or down so that it is the same height as the left-side headlamp.
