Default "Rear Light Failure Warning Light" stays on.

The warning light turns on after brake pedal is depressed on my 2000 Lexus RX300. According to the manual, "one or more stop lights are burned out."

I replaced a couple bulbs two years ago but the warning light does not go away. I want to sell the car but have to figure out the problem so that a potential buyer doesn't think there is a major electrical issue.

Every light works correctly side marker, reverse, plate, turn, tail, brake/stop, etc. Even checked the brake light at top of hatch and made sure that the four tails get bright when brake pedal is depressed.

After a quick search I noticed a few with the same issue. Some recommend using a higher quality bulb unfortunately, no one has confirmed this as a fix.

I know a couple of the tail bulbs have been replaced but don't know which ones. So I have two questions:

1. How do I know which bulbs are factory/OEM by looking at them?

2. Where do I get high quality replacement bulbs, dealer only?

Does anyone have any other solutions? Thoughts?

Thanks.

Make sure the brake fluid level in the reservoir is good.

Check your top mounted brake light along with the two side ones.

The quality does not matter much, but matching the wattage is important. Worst case scenario is that you replace all three [although you can do one at a time a keep moving the good one till the problem goes away]. We are talking less money than the gas in the tank.

I just checked. The wattage is correct on the replacement bulb.

I think my next move is to buy the bulb directly from Lexus.

Did you check the brake fluid level, as was suggested? Also try unplugging the electrical connection on top of the brake fluid container, in case the fluid level sensor switch is defective. I don't recall if that is the proper warning light for that condition, but it is worth a try. If the bulb wattages are really correct, there is no need to get a "Lexus/Toyota" bulb.

All the vehicles I've owned used the parking brake light to indicate low fluid.

I found that rear light indicator related to third brake light in the hatch getting loose. Even when the bulb 'hooks up' again if the warning light is tripped, it stays on until the next start up.
