BOTH 2006-2009 Prius D4R headlight bulbs replaced for $126 total, period. That’s right. Both headlight bulbs replaced for $126.
There are several brands of the D4R bulb. The factory Prius bulbs are from Philips. Since the D4R is a commodity part, in other words it’s made by many manufacturers in quantities in the millions, then Toyota just puts out for a bid and picks the lowest bidder with the best reputation. So Philips is nothing special.If you want to replace your factory Prius bulbs with the factory Philips part, then you pay far more. Fine by me. It’s your money. The issue is still that even after being replaced, they are ‘burning out’, again. Think it’s still the bulb?? The Prius is not the only car to run the D4R. Not by a mile. Do you hear all of these same headlight issues with other brands of cars? Not even! Here’s how industrial design electronics work. A spec is generated and then engineering designs the circuitry to that spec. In good companies they test the daylights out of the part to make sure their spec is sound. If it fails, they make the improvements, and test the daylight out of the improved part. Bad companies will just lower their part price to dump the defective design onto the market. Happens all of the time.
Here’s my take on Toyota’s headlight issue. If the bulbs repeatedly die in a Prius, but not in other brands of cars, then it’s not the bulb, it’s the control module that drives it. When a spec is written, a rookie circuit designer will make sure his circuit meets the spec. He’s fresh out of collage and has a lot to prove. So he works hard. What he is missing is that time is the great educator. He doesn’t know if his circuit design will still work once it ages, or once the bulb ages. Since both the control module and the bulbs are active elements of the design, they are prone to wear. So they can drift out of spec. An experienced designer knows this, and makes sure his circuit is made to work with parts that are very well worn or seasoned. Yes I know they do accelerated age testing. But that ain’t real life. Only real life can show how well something works over time. Everything else is just a guess. Otherwise there would never be a recall on anything. In theory, the design should work. In practice, the theory doesn’t work.
Here is what I am offering. Since the bulbs will most likely burn out again in the future, read about it online if you don’t believe me, then just put in something equivalent until Toyota gets their act together. The lower cost bulbs that are available are not that much lower in cost than the factory Toyota bulbs. Remember any good car maker designs in a significant amount of profit for the parts they sell.So of course they will cost far more than the equivalent parts made by other manufacturers. Is it really worth leaving your car at the dealer, arranging another ride back to work, then arranging yet another ride back to the dealership?? Over light bulbs?
Email me and I’ll schedule you in. I’m at mikep_95133 at yahoo.com. If you want me to come to your work and do it there, it’s another $25. I can take paypal, cash, or even checks if you don’t look like a slime ball. If your check bounces I’ll repo my bulbs
If my distributor runs out, there may be a delay. So far so good. Same with the prices. So far so good on them too.
If you absolutely want the Philips bulb, then pay me in advance and I’ll order them for you. The price will be somewhat higher.
If you already have bulbs, and want me to install them. I’ll charge you $60 total for my labor. I’m just trying to pay the mortgage.
