O-NEX Xenon D1S D1R 35W HID Ballast 93235016 - Direct Replacement

In this review of the O-NEX Xenon D1S D1R 35W HID Ballast the bottom line is straightforward: this is a budget-friendly, plug-and-play replacement for specific factory ballast units that works well when the original unit fails and the headlight housing is dry. The reviewer finds it best for owners who need a direct physical swap for part numbers like 93235016 or OEM equivalents and who value immediate brightness restoration without complex wiring. It is not an OEM part, but it is designed to match factory connectors and mounting for a quick fit.

Key Features

• Pack of 1, factory direct fit: Sold as a single replacement unit that mirrors the original ballast shape so it installs where the factory unit sat.
• Plug-and-Play connection: The unit uses the same connector types as many factory parts so installation is typically a straight swap without cutting wires.
• Wide vehicle compatibility: Compatible with many vehicles including Land Rover LR2, Buick Lacrosse, Aston Martin models and Volkswagen Passat CC when matching the listed part numbers.
• OEM number cross-reference: Supplied cross references such as 3928988158 and 93235016 to help buyers verify fitment against their factory label.
• Brightness restoration: Customers report the ballast restores HID brightness to expected levels when the headlight and bulb are in good condition.

Who It's For

This ballast is aimed at DIYers and independent repair shops replacing a failed factory ballast on compatible models from roughly mid 2000s to early 2010s. It is particularly useful when the original unit has failed electrically but the headlight housing and bulb remain dry and undamaged.

It is not the right choice for owners whose headlights show evidence of water ingress or corroded connectors, since the listing warns a replacement unit can fail again if the housing is compromised. Those seeking a branded OEM module or a lifetime durability guarantee should consider OEM dealers or refurbished factory units instead.

Pros & Cons

Pros

• Direct replacement design makes installation straightforward for many vehicles and reduces installation time.
• Good value for money compared with buying a new factory module, with many customers praising the price-to-performance ratio.
• Restores HID brightness reliably when matched to the correct factory connector and a dry headlight housing.

Cons

• Durability is a concern for some buyers, with reports of failures within weeks under certain conditions.
• Not a genuine OEM part, so fit or long term reliability may vary if the factory ballast was updated mid production.
