E-Code headlamps are very high quality and generally provide more lighting output than their DOT counterparts.
Certainly you’ve heard the term “DOT Approved” and know that it means the lighting product you are using is approved by the United States Department of Transportation to be used on your automobile while driving on public roads. Now, if you do a lot of work with older vehicles and any commercial or industrial vehicle, you may have even heard of “E-Code” lighting products. E-Code, or ECE, is a term used in the European’s version of the American DOT. In short, ECE stands for Economic Commission for Europe and it refers to legislative regulations on all sorts of products sold over the world, but there is a special section of ECE regulations just for automobile lighting products. (The full description of what E-Code or ECE stands for is: “The World Forum for Harmonization of Vehicle Regulations is a working party (WP.29) of the United Nations Economic Commission for Europe”) As of 2009 there are 58 countries that participate in ECE standards, including Germany, Japan, United Kingdom, Australia and Sweden.

Here is a comparison showing stock Jeep headlights to new Autopal housings.

Autopal headlights use replaceable light bulbs so you never have to take your housing out again.
So what does this mean for you? If your vehicle has sealed beam head lights from the factory that are DOT approved, when you replace them with E-Code housings not only will they provide MORE light output, but the beam pattern will be better than before also. Generally speaking, American automobile lighting regulations are very strict, more-so than other parts of the world. There are several brands of sealed beam conversion headlights that provide this upgraded E-Code style headlamp but my favorite is Autopal. I like Autopal E-Code headlights because they are a high quality product made in India with a thick glass lens and a sturdy metal housing-back, but they don’t break the bank like Hella E-Code housings.
Autopal E-Code headlights are available in 5×7, 7×6, 6″ Round, 7″ round, 200mm and 165mm. The other thing that Autopal E-Code headlights are great for are installing an aftermarket HID conversion kit. Because of their unique design you are able to install a shielded H4 HID kit into an H6054 style housing and not blind everyone who you drive next to on the highway. Here are a couple pictures of a 5×7 e-code headlight housing accompanied by a GTR Lighting HID system:

Pontiac Fiero with E-Code headlights and an 8,000K HID conversion kit.
So you can see that even though the Autopal E-Code headlight housings are reflector type, paired with a high quality HID kit from GTR Lighting, they provide a good cutoff line AND superior lighting output. In a sense with these housings you can have your cake and eat it too! Because these headlights come in such a variety of sizes you can fit any sealed beam headlight vehicle with a set of better housings. These types of headlights are available from TLG-Auto for a variety of vehicles including VW Passat, Hummer H1, Hummer H2, Mercedes G500, Pontiac Fiero, Toyota MR2, Toyota Celica, Mazda Miata, Jeep Wrangler, Jeep Grand Cherokee and many more vehicles including semi trucks and tractors.
