Hella 165mm H1 Conversion High Beam E-code Headlamp SKU: HL79565

For thirty years SUSQUEHANNA MOTORSPORTS has sold to the public at “Jobber” or wholesale prices. Because of a few bad actors who used their buying power to undersell everyone else and drive many out of the market, Hella has instituted a MAP (Minimum Advertised Price) effective April 1, 2024. This prohibits anyone from ADVERTISING certain Hella products at prices below those on Hella’s MAP list. MAP prices are the same as MSRP (Manufacturers Recommended Retail Price) and are higher than Jobber and considerably higher than those advertised on several websites. Violators will be placed on a “No sell” list and will no longer be allowed to buy directly from Hella. We will continue to sell those items at Jobber prices until March 31 at midnight.

Sealed beam headlamps were introduced in the 1930s to provide a consistant quality of headlamps. Prior to that, headlamp design was left up to the vehicle manufacturer and lighting ability varried greatly.

The problem with sealed beams is that the lens, reflector and fillaments 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.
