RANSOTO DDLT003 Xenon HID Headlight Ballast Control Unit with Igniter D4S Bulb Compatible with 2006-2012 Lexus IS250 GX460 ES350 GS300 GS350 RX350 & Toyota Prius Avalon, Replaces 85967-52020 KDLT003

The RANSOTO DDLT003 Xenon HID Headlight Ballast Control Unit with Igniter and D4S bulb is an excellent replacement for my Lexus. The installation was smooth and it fit perfectly without any adjustments needed. Once installed, the headlights powered on instantly with no flickering or delay, providing bright and stable illumination. I really appreciate that it comes as a complete kit with the igniter and bulb, making it a hassle-free solution. The build quality feels durable and well-made, giving me peace of mind for long-term use. It’s also a great value compared to dealership prices, yet performs just as well as the original part. Having clear, bright headlights again makes night driving so much safer and more comfortable. I highly recommend this ballast kit for anyone needing a dependable and cost-effective HID headlight replacement.

Cheap replacement for the OEM I had that went bad. Now my high beams work again.

Excellent

So far so good. Easy to install.

Warning: NOT OEM duplicate. For 2007 (and presumably other Generation 2 years) Prius: this Ransoto DDLT003 85967-52020 Xenon Headlight Ballast [ASIN B08KZM31MG] REQUIRES careful de-soldering & soldering lamp ground (unlike Toyota OEM & others after-market parts) to avoid re-leveling headlights! Toyota screwed all its 2007, et al, HID Prius customers in as much as both changing a headlight lamp and or a headlight ballast is a pain in the rear. With only 142,000 miles, I've had to change both head lamps 3 times and both ballasts twice! Neither of these processes are easy, ESPECIALLY changing the HID ballast. First pain in the rear: The 2007 Prius HID headlights are part of a large assembly including running and turn signal lamps. Removing the headlight assembly REQUIRES loosening and partially removing the front bumper cover. Once the headlight assembly is removed, access to the ballast is from the assembly bottom, the ballast being retained by 4 SS PH screws. Once partially removed, one can see the ballast has 2 cables connected, ONLY ONE of which is removable. Now the VERY BIG PAIN IN THE REAR: The ballast to headlight lamp NON-REMOVABLE cable has a high-temperature lamp connector that is too large to pass the interior parts of the headlight assembly. One has, apparently, only two BAD choices: A) partially disassemble the headlight assembly and then later realign the headlights; or B) disassemble the high-temperature HID lamp connector, and then reassemble after fishing its cable through the headlight assembly confined interior. Regarding Choice A: Realigning headlights is NOT likely to be accurate unless one FIRST creates accurate and repeatable vehicle, floor, and PRECISE wall targets for BOTH headlights BEFORE doing ANY disassembly. Given the safety hazard created by misaligned headlights, I have chosen to not choose Choice A. With the Toyota OEM ballast, Choice B is a pain as connector disassembly is clearly not planned, but it can be done with a small flat-head screwdriver and a knife blade. Once disassembled, both the red (hot) wire and white (ground) wire are terminated to contacts that are easily removed from the black plastic insulating connector housing. Other aftermarket ballast manufacturers (that I purchased and which have been documented by others on DIY web sites and videos) have duplicated Toyota's OEM ballast high-temperature 23,000 volt HID lamp connector red and white wire contact terminations. This Ransoto DDLT003 85967-52020 Xenon Headlight Ballast [ASIN B08KZM31MG] does NOT duplicate the Toyota OEM ballast ballast to headlight lamp NON-REMOVABLE cable high-temperature HID lamp connector wire termination. Instead, the white (ground) wire is soldered to the connector contact, REQUIRING careful de-soldering the wire termination, and then even-more-careful re-soldering after fishing the high-temperature cable through the headlight assembly confined interior. Learning how this Ransoto ballast was different easily pentupled the total task duration AND required that I setup de-soldering/re-soldering equipment and station unexpectedly. If you have a Generation 2 Prius, do NOT purchased this Ransoto ballast unless you have high-voltage soldering experience and equipment—the HID ignition requires 23,000 volts momentarily! I would NOT repurchase this Ransoto DDLT003 85967-52020 Xenon Headlight Ballast [ASIN B08KZM31MG]. In fact, I would have returned it except I had already removed both headlight assemblies before learning of the serious design flaw.

Product is very bright nd worth the money and the right size that fits very good and very compatible and great quality

I was concerned at first when the part number didn't match my OEM ballast, but everything plugged in and works. Now I think I need to replace the other bulb as it is dimmer than this new one. Tip: the large connector does not willingly pass through the inside of the light (which is unfortunately normal for OEM headlights). Remove the headlight adjuster and anticipate a little prying to get the headlight cable to pass through.

I ordered two and received both within the timely fashion as expected. However, one ballast quit working after about three months. Which was about two months ago. Why I am just now taking action is beyond me. Nonetheless, Ransoto states they offer a six month warrenty in which I would appreciate claiming. What’s unfortunate is I cannot find the “Contact Seller” hyperlink anywhere and the time frame is outside of Amazons Policies so it is rather difficult to handle this situation without anyway to directly contact the seller. I purchased the ballast on February 24, 2025. Therefore I should still be inside of the six month period of said Warranty. How do I know it is the ballast and not the bulb? Simple, I swapped the currently working bulb from the working ballast and it would not light up inside of the presumably dysfunctional ballast. I even tried another bulb that I so happened to have and still nothing. So I have been driving around with one headlight yet again and would sincerely appreciate it Ransoto if you would send me a replacement or contact me or something. Other than that the working ballast and bulb is sufficiently bright and works as expected. Was delivered on time and everything else is a plus but there does seem to be an ongoing trend with a few folks on here who have also experienced a similar situation. So I guess you get what you pay for which as long as they keep burning out before six months is up, I’ll be set for a while. However, it certainly isn’t the most simple task to accomplish having to break down the front end just a bit. It just isn’t the most exciting happening but I’ll do whatever needs done to ensure I do not get pulled over. Otherwise I will have a heap of other issues I am currently not prepared to deal with. Not now. Not ever. So again, Ransoto, please help me out here and let’s make some follow through happen. Thank you.

Working very good. It is as good has the Venza one.

Good packing/ quick delivery - It is much easier to drop the front buffer slighlty, slide the big front lights out and remove the old controlbox, carfully unclip the light holders/ replace the new tubes - than to try doiing this from under the car. Sofar - excellent bright lights!
