OEM Denso ballast

Perfect place to get ballast (AND bulbs) for my customers. I shop around, but always come back to HID Concept

OEM Lexus HID ballast

Great place to shop for your auto lighting needs. I come back often for my customers at the shop. Good price and great service.

Great deal

I found a couple of places in Nova Scotia that sell the genuine Denso HID ballast, but the price was just really too much. I found HID Concept via Google search. Even with the DHL cost, getting two ballast was way cheaper than getting them from here.

Denso ballast

Good price for a genuine Denso ballast. I found a lots of copied versions, but for this price, it wasn't worth getting the copied version.

Genuine denso ballast

The price for this Denso ballast was great here. I purchased two and Philips D4S HID bulbs for my Lexus. I spent a little more than I was going to initially, but I figure that doing everything at once would save me the time, money and less headache down the line.

Lexus HID ballast

I bought two replacement ballast for my 2011 Toyota Avalon. I saw HID Concept's OE-PART but just felt comfortable buying the genuine parts.

Nothing beats the original

I use some copied version ballasts for cars, but for some reason, all the Lexus customers want the genuine ballast. Not a problem. I come to HID Concept to get the Denso ballast(s) The price is very good for the genuine stuff and the shipping is free!

Replacement HID ballast

Why would anyone buy auto parts from the dealership? This DDLT003 price was about 4 times higher at the dealership than HIDCONCEPT! Great price for a genuine product.

Denso DDLT003

Got a pair of genuine Denso DDLT003 at a great price. Seriously better price than at the dealers.

HID ballast DDLT003

Very nice price for Lexus replacement ballast. HID Concept had the genuine stuff.

The installation was not as bad as I thought. Good thing I didn't go to the dealer to get it replaced. Saved a lot of $$$ by just getting the ballast from HID Concept.

Lexus ballast

Great price. Compared few other places, and HID Concept had the best price for a real ballast.

Beats dealer's price

My Lexus dealer wanted over 300 bucks for Denso HID ballast, and that's not even including the labor cost! I got one from HID Concept at a far better price and extra saving with the online coupon code .

Denso DDLT003 HID ballast

Genuine Denso ballast at a great price. David at HID Concept recommended replacing both ballast, so I got two.

Denso DDLT003

I was reading the other reviews, and the dealer price keeps coming up. That is so true though. To be exact, $ 297.87! Never going to the dealership again for parts.

Lexus HID ballast

Easy purchase. genuine Denso hid ballast for my lexus. Had my mechanic replace the dead one and he asked about the price. I told him. He asked for HID Concept web addy. Nuff said.

NOT some fake cheap Denso ballast but the real thing at a great price. Thanks, HID Concept!

Denso D4 ballast

I found some copied version at ebay, but didn't want to take a chance and got the real thing from HID Concept.

Super price

Super price for a real Denso HID ballast for my Lexus. I thought about buying a copied version from ebay, but decided not to take a chance with it. The dealer price was over $250!

For my Lexus

One of the ballast went bad on my good old Lexus. I was going to replace just the bad one, but at the price, I found at HID Concept, I decided to replace both. I like my Lexus dealership and all, but the price can't even be compared with HID Concept. Good store.

Excellent real Denso ballast

HID Concept had the real Denso ballast that I wanted at a fraction of the dealer's price

Denso HID ballast

Searched the web and found HID Concept. Their price was better than the dealers for sure, and from other online sellers. Got 2.

Lexus ballast

I work on Lexus a lot, and I usually come to HID Concept to get the lighting needs for my customers. Good price, easy transaction, and pretty fast delivery.

Denso D4 ballast for Lexus

Simply, do not go to the dealer to get these ballasts. They will totally charge you 150% more than HID Concept.

A complete set of Philips/Denso ballast

EXCELLENT DEAL! My Lexus had a bad deal with some water damage to the headlight units. The cost of replacing/fixing was stupid expensive. I searched online and looked at some forum, and found HID Concept with a complete Philips D4S/Denso DDLT003 HID ballast set. Saved lots of money.

Denso ballast and Philips HID bulbs

This truly is a great set price for two Denso D4 HID ballasts and two Philips D4S HID OEM bulbs. Highly recommend

Two blown ballasts and one Great deal from HID CONCEPT!

What's the chance of having both ballast controller going out at the same time??? I thought I'd have to give up a month's pay to get them replaced at the dealership. My trusty mech told me about HID Concept and the price for TWO Denso ballast and TWO replacement bulbs were just incredible. I actually had my mechanic ordered me the correct bulbs (I know nothing about cars) and the shipment came within 3 days (free shipping, thank you) and now I got a nice set of headlights at such a great price. I'm recommending HID Concept!
