DESCRIPTION

BETTER THAN OEM HID UPGRADES.

The D4S Xenon HID kit produced by Philips and Osram is 25W without a capped brightness of 2000 Lumens. It's capped at 2000 Lumen so car manufacturers are not required to fit auto-leveling and washer systems. The very best Xenon kits found in the high-end euro cars are all equipped with 35W units from the factory.

 

PLUG & PLAY.

Unlike other retro-fit solutions on the market, our D4S doesn't require any adaptors or wiring hacks. Just like the original equipment, our D4S kit integrates the starter and igniter in the base of the unit and will plug directly into your factory headlight wiring harness. We expect that the installation can be carried within 10 minutes. 

+79% LUX | +42% IN LIGHT VOLUME.

A huge increase in visibility without sacrificing longevity. The Xenon gas used in our D4S is supplied by Messr™ Germany. The capsule comes from APL™ in the USA. The Quartz glass is Philips™.

    The book itself is excellent, very helpful with lots of specific information. I was disappointed (one star) that the used hardcover edition I ordered arrived as the paperback edition, though in very good condition.

    Simply what any serious would-be writer must know.
    Format: Kindle
    I am a writer only in the sense that I write daily and believe that I do have that ineffable "it"; I do not, however, have any formal writing training. I say all of this to make clear that anyone, literally, can read and understand this book, gaining invaluable knowledge about the craft of writing. Some of the less effulgent reviews of this title have pointed to the "pompousness" of Prof. Gardner and his supposed sesquipedalian loquaciousness as reasons for hopeful writers to search-out more simplistic guides. I disagree emphatically. I truly believe that this book holds the keys to unlocking the divide between the good and great writer, particularly for those of us who have not had access to the best educational opportunities. Personally, I want to be a great writer. Not a good writer, not a successful, or published, or wealthy writer: a great writer. I want to move people to think about things in ways that they never would have, maybe without even knowing that their ideals are changing; I want to move people! To write like that one needs, me thinks, the guidance of one with an intimate knowledge of how this is properly -and not so properly- done, and the "arrogance" to believe he can convey this understanding, even to we ignoramuses. This is what I have found in Prof. Gardner and this wonderful tome. Distracters may feel free to criticize my review as they wish. I stand by my opinion of this book and its Author.

    I Recommend It, But Not Much
    Format: Paperback
    This book is recommended in SELF-EDITING FOR THE FICTION WRITER, a book I have read twice and enjoyed a great deal. I had to give Gardner a try. This is a tough review to write because I can't say this is a fantastic book to help one write fiction. At the same time, there is little or nothing said that I disagree with. So, what's the problem? My confusion starts with my expectations when reading a book about writing. It's a situation where I want to gain information and hints on how to write better, without being bombarded by direction on how to write. This criteria has served me well and I've found a number of writing books that made me write or want to write better; SELF-EDITION FOR THE FICTION WRITER is one, THE FICTION WRITER'S WORKSHOP is another. Judging by that, this book didn't pass muster. Rather than coming away with a new awareness of what I want to include or exclude from my own work, I'm left feeling like I've been having coffee with an experienced author full of sweeping opinions on craft. He's crafty in one way, his ability to pull me in with the sense of being an insider, watching other fiction writers through thick glass. He uses a lot of lines like "The writer who can't distinguish truth from a peanut-butter sandwich can never write good fiction. What he affirms, we deny, throwing away his book in indignation..." The implication isn't about writers of bad fiction so much as it is about 'us', him and I, being partnered in our unique ability to indignantly recognize a lousy writer. In fact, we're pretty decent to only discard the book when we're entitled to exact creative justice on its sloppy author. Still, and here's the rub, it isn't a bad read. Don't skip an hour of writing to sit down with this book but if you're between projects and have the time, I'd recommend it.

    Good Guide to Writing in General
    Format: Paperback
    What Gardener says about fiction can equally apply to writing any good prose. He was a master teacher and this book definitely shows his skills in conveying the underlying knowledge to others.
