Isuzu Amigo Back Up Light Switch Guide for 1998-2000 Models
Fix your reverse lights for good by choosing the right replacement switch for your Amigo.
- The most common reason for reverse light failure on an Amigo is a bad back up light switch, but always check bulbs and fuses first.
- A frequent failure point is the wires breaking off the switch body; inspect this on your old part.
- This is a very DIY-friendly repair that can be done in about an hour with basic tools.
- Quality aftermarket brands like Standard, Facet, or Vemo are reliable and cost-effective alternatives to a more expensive OEM part.
Is Your Amigo's Back Up Light Switch Failing?
A bad back up light switch is a safety issue, as other drivers and pedestrians can't tell you're backing up. Before you blame the switch, always check the simple things first: make sure the reverse light bulbs aren't burnt out and check the fuse for the backup lamp circuit. If those are fine, the switch itself is the next logical part to inspect.
Key Symptoms of a Bad Switch
- Reverse Lights Don't Turn On: This is the most common sign. You shift into reverse, but the lights at the back of your Amigo stay off.
- Lights Work Sometimes: The lights might flicker or only work when you wiggle the shifter. This can point to a worn-out switch or a loose wire.
- Reverse Lights Stay On: In rare cases, the switch can fail in the "on" position, causing the reverse lights to stay lit and drain your battery.
Known Issue: Broken Wires
A very common failure point on the original Isuzu back up light switches is not the switch itself, but the wires connected to it. The wires can become brittle over time and break right where they enter the epoxy body of the switch. When you inspect your old switch, check for this problem first. If the wires are broken, the switch must be replaced.
Choosing the Right Aftermarket Switch
For a vehicle like the 1998-2000 Amigo, aftermarket parts are the most common and practical choice. The original Isuzu part may be available, but it is often more expensive. Aftermarket quality for a simple switch like this is generally very reliable.
- Premium Aftermarket (Facet, Standard Ignition, Vemo): Brands like Standard Motor Products (SMP), Facet, and Vemo are well-known for producing quality replacement parts that meet or exceed original specifications. Facet and Vemo are European companies that position themselves as high-quality alternatives. These are excellent choices for a reliable, long-lasting repair.
- Value Aftermarket (Replacement): Generic or store-brand "Replacement" switches offer a lower price point. They are functional and will get the job done, making them a good option for budget-conscious repairs.
Pro Tip: When buying your new switch, look at the point where the wires attach to the switch body. A switch with a well-supported, flexible wire lead may offer better durability against the vibrations that can cause the original to fail.

Frequently Asked Questions (FAQ)
Where is the back up light switch on a 1998-2000 Isuzu Amigo?
The switch is located on the transmission. For manual transmission models, it is usually screwed into the right-hand (passenger) side of the transmission case. You will need to safely get under the vehicle to access it.
Can I replace the Amigo's back up light switch myself?
Yes, this is a good DIY job for someone with basic tools. The process involves disconnecting the battery, unplugging the switch's electrical connector, and unscrewing the old switch with a wrench or deep socket. The most difficult part is often just reaching the switch on the side of the transmission.
Are there any recalls for the Isuzu Amigo back up light switch?
No, there are no specific recalls or technical service bulletins (TSBs) from Isuzu or the NHTSA for the back up light switch on the 1998-2000 Isuzu Amigo.
How can I test my back up light switch?
After removing the switch, you can test it with a multimeter set to continuity or resistance (ohms).

When you press the plunger in, the meter should beep or show a closed circuit (near zero resistance), indicating the switch is working.
