Replacement Bulbs For 1990 Ls400 Instrument Cluster

Recommended Posts

What are equivalent aftermarket bulbs/lamps (mfg and #) for a 1990 LS400? Preferably, name-brand (eg, Phillips, Sylvania, etc) "long life" bulbs, which are usually rated at 14V, I believe.

The bulbs in-question are:

A: 16 miniature (< 1/2 inch long) bulbs that insert into the back of the Combination Meter (aka, "instrument cluster"). These bulbs have wedge bases that push into blue plastic twist-in bases.

PLUS...

B: 8 miniature ( < 1/2 inch long) bulbs that go into the Warning Light Assembly (which is located above the Combination Meter and reflects downward on the front of the Combination Meter "glass"). These bulbs have pig-tails that are threaded through holes into gray plastic twist-in bases. These bulbs - since they don't have a wedge base - are slightly shorter than the bulbs in "A" (above).

I want to replace ALL these bulbs while I have the cluster pulled to repair the speedometer. At 20 years old, a couple of the bulbs are out, and I expect it's only a matter of time before they begin dying en-masse.

BTW: the speedo was reading too low, but I discovered that all I had to do is move the needle upward a little to fix the problem.

The Lexus dealer wants over $7 EACH for these bulbs!

Thanks!

Unfortunately they're a very unusual size... i doubt you'd be able to get them from Autozone or alike stores.

Can you post pics of a few? I might have some from recent projects, i know i have slightly used ones somewhere (from 2003 Rx300) and if they're the same size they'd work great.

Here's a photo showing the two types of bulbs. The wedge-base is on the left, along with its plastic base. The pig-tail is on the right, with its base (but minus its pig-tails, as they are broken off).

I normally put my photos on a hosting site like photobucket.com then paste the direct link onto the forum
